10 MHz Reference Extractor Thru Tee

The Orbital 10 MHz Reference Extractor Thru Tee (RET-25/40) is a unique bias tee thruplexer (thru tee) that does more than pass L-band and 10 MHz and insert external DC: it extracts the 10 MHz reference signal from the modem. The demultiplexed signal can be used for monitoring purposes or as the timing reference for additional devices – such as a redundant LNB or BUC. This RF component can help SATCOM system integrators and 4G and 5G cellular network operators reduce costs, simplify designs and eliminate multiple clock sources.

  • Filters L-band and 10 MHz, inserts DC
  • Extracts 10 MHz reference signal
  • Choice of connector type and mounting options
  • High return loss and low thru loss performance
  • Only 3.5 dB of signal loss for demultiplexed signal

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.

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.
