Mid-Atlantic's Multi-couplers are intended for use with analog Video (0 to 2V) and TTL (0 to 5V) distribution systems. They provide a low cost means to provide a number of channels of RF or TTL Logic signals from an antenna or other source to three individual loads. The unit is specified to operate over wide frequency range, and is fully tested to assure compliance over that range. This unit is designed to be rack mounted into an EIA 19 inch “relay” rack and has all connections made to the unit’s rear panel. The front panel contains only the power switch which has an LED power indicator which illuminates when the unit is powered.


Controls include an AC Power switch on the front panel and gain and DC offset trim adjustments for each of the output channels on the rear panel. Internal circuits are forced air cooled. Standard operation is with forced air cooling always on, but an option is designed in to control the forced air cooling via the internal temperature. Gain trim is set to unity during factory test. DC offset is set to 0VDC during factory test.


Mid-Atlantic RF Systems can customize these units to exact specifications required by customer.

Receivers / Tuners

The LCR series of tuners/receivers provide a low cost solution for an assortment of military and commercial applications. The double-conversion superheterodyne receiver with integral synthesizer can be configured with a 160 MHz IF output/100 MHz bandwidth or a 1 GHz IF output/500 MHz bandwidth. The small, lightweight tuner/receiver covers the frequency range from 0.5 to 18 GHz, with a tuning step size of 1 MHz. Modular packaging permits a variety of physical layout options. The LCR circuitry is contained in two 2” x 3” x 1” modules. RF input and IF output functions are completely contained in one module. The 1st and 2nd LO functions are in a second module. Multi-channel receiver configurations can be constructed easily with a common LO module and multiple RF/IF modules.


A ruggedized package option is available to meet more stringent environmental requirements.


Note: Customized versions of the standard product can be supplied.

Mid-Atlantic RF Systems designs and manufacture RF Synthesizers Modules for a wide variety of applications. They are typically use as high performance sources in applications where performance is paramount. Mid-Atlantic has designs based on both DDS (Direct-Digital-Synthesizer) and PLL (Phase-Locked-Loop) architecture so that customer can decide on which type best fits their application. Synthesizers can have either self-contained internal references, or be locked to an external reference. Synthesizers are typically controlled via TTL control. Optional modulation input is available. Custom designs can also be designed to meet your unique specifications.
