The Orbital Research “Mux Tee” (MT-25/40) is a premium bias tee multiplexer that does much more than insert DC current: it multiplexes a 10 MHz reference signal onto the L-band signal. And because it is a passive device that requires no power, it can work in reverse and extract a DC signal and/or demultiplex a 10 MHz reference from your modem.

The Mux Tee is 6 devices in 1:

Bias tee
10 MHz multiplexer
Both a bias tee and 10 MHz mux
DC extractor
10 MHz demultiplexer
Both a DC extractor and 10 MHz demux

The Mux-Tee filters the incoming IF signal and provides an effective block to any unwanted DC or 10 MHz that may be coming from the modem – delivering exceptional return loss and very low thru loss. In addition, the external DC and 10 MHz inserted signals are filtered to avoid any interference with the wanted IF signal.

Applications

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 the 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	The modem has DC power, but not enough to power my new BUC.
4 Way Combiner with 10 MHz Oscillator and High-Power DC insert.	I want to lock several modems to a single 10 MHz Oscillator and insert high-power DC into my BUC.
Orbital 2-way Combiner using 10 MHz from one of the modems and High-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 a 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 MT25/40 Mux-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. This product may be used in its standard orientation, (as shown), or in reversed position – to extract, rather than insert 10 MHz signals and DC current.

Warranty: 3 years, repair or replace defective product

Each connector type has an impedance of either 50 or 75 Ω. Orbital uses 1 of 4 distinct boards to achieve the appropriate impedance transform:

V1 – 50 Ω to LNB/BUC, 50 Ω to Rx/modem
V2 – 75 Ω to LNB/BUC, 50 Ω to Rx/modem
V3 – 75 Ω to LNB/BUC, 75 Ω to Rx/modem
V4 – 50 Ω to LNB/BUC, 75 Ω to Rx/modem
International customers should note that pricing does not include freight, brokerage, local VAT, and customs charges. Prices from our dealers in your area usually include these amounts.

The Orbital MT25/40 is a Bias Tee (and a Diplexer, and a Mux-Tee…)

Orbital MT25/40 Mux Tees function as bias tees (inserting DC power into the combined signal), as diplexers (inserting 10 MHz into the combined signal), and as mux tees inserting both DC power and 10 MHz reference). The MT25/40 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.

MT25/40’s also work in both directions – in reverse position, they can extract L-Band or 10 MHz signals.

The MT25/40 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.
