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 any commercial application including 4G and 5G cellular networks.
Filters L-band/10 MHz signals and inserts DC

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.
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.
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.

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.
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.
