The Orbital RET25/40 Reference Extractor Thru Tee is built for indoor mounting back-o-rack, but its ‘O’ ring sealed connectors and corrosion protection due to its Anodized finish, also allow for outdoor use. The RET-25/40 functions as a Bias Tee Throughplexer and a DC extractor. It allows for DC power from the modem to be extracted at the dish to provide power to a second device. Alternatively, it allows for insertion of additional DC at the dish

Flexible Solutions:

An Orbital RET25/40 Extractor Thru Tee works as a Thru Tee – passing L band, 10 MHz reference, and DC power.  It also extracts the 10 Mhz reference  from the inter-facility link for use at the dish and allows for secondary DC power input.  It performs low-loss impedance transforms, it filters and cleans the L band, DC power and 10 MHz signals.  Many of our clients have taken the trouble to call and comment on just how much the Orbital Mux Tee has improved their system performance.

Made for Professional Use, Made for Satellite:

Orbital Systems Interface Products are made specifically for the satellite industry, and are designed for professional and industrial quality systems.  Orbital SIP products are built for rack mounting, and for use indoors or out.  They are also perfect at the dish or in the rack for creating a test point for live signals – without degrading ongoing operations.

Why would I want a Bias Tee Multiplexer?

  • Most engineers are aware that with mux tees and diplexers, the phase noise performance of the system – specifically the local oscillator in the LNB, (or the local oscillator in the BUC), is totally dependent on the quality of the10 MHz oscillator.   While you can buy a very high quality, very low phase noise, very stable product – getting from that oscillator to the LNB or BUC can create problems if not done correctly.  For example, if you amplify and split the 10 MHz signal, you are going to have to ensure that the amplifiers are very low noise, that there is no VSWR issue, and that there is no contributed base noise issue.  With an Orbital product taking over that task for you, you are assured of no added noise, no problems with, or distortion of the 10 MHz signal as it is going from the oscillator or to the LNB or the BUC.
  • You’ve got a redundant switch, you need to power your LNBs separately, so one of them is always on and not being switched by the switch, so you use a bias tee, or a Mux for an external reference unit.  Or you have a redundant system and you have to be sure that you’re not switching your 10 MHz, because you’d use lose lock on the LNB you switched to.   You have to have a splitter feeding to the LNB all the time, not switched, but to do that you need two Mux/Tees feeding 10 MHz constantly into the LNB, and only the output gets switched.
  • Anytime you have to split a signal, go to multiple receivers or multiple modems, the safest way is a Mux/Tee or Bias Tee.  Anytime you have to use multiple modems to feed a BUC use a Mux/Tee, or Diplexer if you are powering the BUC separately.   An Orbital SIP product guarantees performance, filtering, conditioning, no degradation of signal, no ripple problems, and you can transfer impedances at will.  Saves time, saves money, it raises system integrity, reliability, and performance.
  • You’re a sophisticated systems system integrator, you have field technicians, you have system engineers in the field, and you’ve got a lab – what are they using for test purposes?  They should each have a bias tee mux in their tool kit, to able to insert and test systems so that they can be assured that there is no problem with bias tee, or they can use it to isolate and diagnose system problems.  So there should be a bias tee/mux in every toolbox.
  • In the lab you have to assure quality measurements, sometimes accurate to better than a tenth of a dB – this is where SIPs really shine.  Lab grade products come complete with plots that will indicate the exact loss at each frequency.  It will indicate the insertion loss of the 10 MHz, it will give you the isolation value of the 10 MHz back to the receiver, and will assure best match between each of the components on your bench as you’re testing the equipment.  In other words, you can trust the results you get by using this device to insert – that applies to noise figure measurements, gain, ripple, temperature measurements, anything you’re testing in the lab, is enhanced and made more certain by using an Orbital Mux/Tee.
  • One of the issues we faced was that we were not very satisfied with the quality of the connectors available in the satellite industry.  You can buy very good connectors at a $150 each, and you can get very poor quality connectors all in the same system, yet the signal is serial, it goes through each one of these connectors, good and bad. The reliability of your system is equal to the reliability of the weakest link in your serial signal chain.  The lowest common denominator is going to be your floor of reliability.  Therefore we elected to build our own specially designed connectors, that are interchangeable, to allow low-cost production and re-configuration to different impedances and different connectors, and to provide top quality performance above two GHz, which is not the norm, for example, for F connectors.  So, by taking control of the connector interface and standardizing its mounting system, we have been able to provide you with maximum choice and flexibility at minimum cost, and yet maintain standards of performance that are redefining the industry standard.
  • Consistency and reliability, from system to system in large networks, whether they are VPNs or business networks or broadband networks is essential.  Being able to standardize on a high quality, reliable and repeatable product is important in your overall system five nines reliability.  Remember, quality of service is an important metric these days.  The cost of a service call, the cost of a failure, the downtime of a satellite system, it doesn’t matter what fails, whether it’s a thousand dollar component, or a one dollar component – you are still down. You can count on the reliability of the Orbital Mux Tee.  It will be the same in Brazil, in the North West Territories, in South America. at the south pole, in Equatorial Africa, on the Saudi desert, it will work the same no matter where you are.  You are able to get interchangeability of all of your components because you know that you are connecting to a gold standard product.
  • Documentation in commissioning the system is also important for large earth-station customers.  Orbital, with its state of the art lab, and industry standard equipment from vendors such as Hewlett Packard, Rose and Schwartz, Agilent, Anmitsu, maintain the highest standards of testing and certification of their product.  We can provide plots and back up every measurement that we make, not with just figures on a page but with actual measured instrumentation and plots of performance – so that you can introduce these into your commissioning documents, to verify and validate the performance specifications that are claimed.  This is particularly important for any Intelsat earth-station, any large scale telecom earth-station, and military applications where system documentation and performance and the ability to log the aging of a system is a matter where you have to have well-documented references or starting points

SIP Solutions

Systems Interface Products Although Combiners and Oscillators are also SIP products, we have narrowed the definition here to just include Bias Tees, Diplexers, Mux Tees, TTL Switches, Thru Tees, Dual Power Tees, etc.
Here are standard applications for each of these products. Here’s how to insert 10 MHz, insert DC, extract 10 MHz, block DC, extract DC, multiplex DC L band and 10 MHz, and perform impedance transforms while you do it.

Using a Hi Power Thru Tee to power a BUC Modem has DC power, but not enough to power my new BUC.
4 Way Combiner with 10 MHz Oscillator and Hi Power DC insert. I want to lock several modems to a single 10 MHz Oscillator, and insert high power DC to my BUC.
Orbital 2-way Combiner using 10 MHz from one of the modems and Hi Power Mux/Tee to insert DC power I have a pair of modems, one of which provides a 10 MHz reference, but I don’t have enough power from my modem for my new high power BUC.
Orbital Combiner/Divider stripping out the 10MHz from only one of two modems I have a pair of modems and I need to use the 10 MHz reference from one of them and split it. I need to take the L-Band signal from both modems and combine it with the 10 MHz reference. Now I need to insert DC power for a pair of high power BUCS.
Orbital Combiner/Divider using a MOS 10 MHz Oscillator I need to combine the L-Band signals from a pair of modems with an common, external 10 MHz source, and insert power to a pair of high power BUCs.
Using an Orbital Hi Power Thru Tee to circumvent a divider or switch My modem does not have sufficient DC to power my BUCs, and I can’t switch DC power to the BUC, what to do?
Horizontal/Vertical Polarity 1 for 2 Redundant System We need a system that will provide us with both horizontal and vertical polarities at Ku Band. In addition, the system must offer 1 for 2 redundancy.
