Bias Tees, SIP

Orbital DC Power Extractor Thru Tee

The Orbital DC Power Extractor Thru Tee (DET-25/40) taps off the incoming DC from the modem and splits it between the combined port to the LNB/BUC and a separate DC-only port – so you can power an external device at the antenna. It also acts as a bias tee thruplexer (thru tee) and filters L-band, 10 MHz and DC signals.

The primary purpose of this product is to provide an easy source of DC voltage at the antenna without having to run a separate power cable, however it can also take in an external DC input. The higher DC voltage between this input port and the DC from the modem is applied to the output port to the LNB or BUC. This unique feature opens up may possibilities for the system integrator – such as creating a back-up power source for the LNB or BUC.

  • Filters L-band, 10 MHz and DC signals, inserts DC (optional)
  • Extracts DC power from the modem to power an external device
  • Low insertion and thru loss
  • Choice of connectors and impedances
  • Customizable form factors and mounting options

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.

Mechanical Drawing

The Orbital DET25/40 Extractor Thru Tee is built for indoor mounting back-o-rack, but its ‘O’ ring sealed connectors and corrosion protection due to its Allodyne finish, also allow for outdoor use. The DET-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 DET25/40 Extractor Thru Tee works as a Thru Tee – passing L band, 10 MHz reference, and DC power.  It also extracts DC power 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.

The Orbital DET25/40 is a DC Extractor, that has an optional DC insertion port.
You need a higher power BUC, but your modem cannot supply adequate DC. You need a bias tee and a separate power supply. Plus you need the 10 MHz signal to be split, half continuing through to the BUC and the other half for the system. Conventional Bias Tees shunt the 10 MHz reference signal to AC ground.

The Orbital DC Extractor Thru Tee is a unique device, an industry first, that passively extracts and filters the 10 MHz from the modem, then divides the 10 MHz with over 30 dB of isolation between outputs, and only 3.5 dB of splitting loss, all without adding phase noise. One 10 MHz output is fed back to the BUC insertion circuits, and the second output is fed back to J4 for use as you see fit.

As with standard Orbital Bias Tees, the Extractor Thru Tee allows the injection of up to 2.5A (standard) and 4.0A (high power) of current at 12 to 24 or 12 to 48 volts DC respectively.

The DET25/40 will also act as a DC block on the combined input port – thus allowing DC to be inserted.  It can also act as a low-loss impedance transform, depending on which connector combinations are chosen.

The DET25/40 has less than 0.5 dB of insertion loss and filters and conditions its incoming signals.  It is the fundamental component of Orbital’s signal routing solutions.
