Bias Tees, SIP

Orbital Thru Tee (Bias Tee Thruplexer)

The Orbital Thru Tee (TT-25/40) is a bias tee “thruplexer” that passes both L-band and 10 MHz signals between your modem and low noise block downconverter (LNB) or block upconverter (BUC) – in addition to inserting an external DC power source of up to 4.0 amps. The Thru Tee uses internal filters to block DC from the modem and minimize 10 MHz noise – delivering extremely low thru loss and very high return loss. Primarily designed for the satellite communications industry, the Orbital Thru Tee is also a good fit for 4G and 5G cellular networks.

  •  Filters L-band/10 MHz signals and inserts DC
  • Choice of connectors and mounting options
  • Customizable form factor
  • Stackable with other Orbital products

This product often used to allow insertion of DC voltage where the indoor modem/equipment either has no ability to provide DC on its IF Receive interface or cannot provide sufficient power for the outdoor LNB/BUC.

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 TT25/40 has a selective filter network that filters and passes both 10 MHz and L band while it inserts DC power.

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.

Mechanical Drawing

The Orbital TT25/40 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 TT-25/40 is the Bias Tee you’ve always wanted – it passes the 10 MHz as well as the L-band signal while you insert DC power, and it has a spare 10 MHz port to monitor the reference signal.
