MR Series Frequency Agile Receivers MAY 2013 Data Sheet The most important thing we build is trust The MR Series of receivers from Cobham are advanced technology microwave receivers capable of operation at 1.7 – 2.7 GHz standard. The MR Series demodulates one video and two audio signals from a composite analog RF source. The receiver is controlled by a microprocessor with an easy-to-use menu. Channel of operation, video and audio output levels can be selected via the front panel membrane switch. Operational parameters are shown on the easy-to-read liquid crystal display including channel, signal strength, output level, and lock status. Both digital and analog representations of signal strength are incorporated to facilitate path alignment. The MR Series receiver can also be controlled with a Cobham hand-held controller. The MR Series features an internal 5 pole band pass filter and Low Noise Amplifier at the RF input with a normal noise figure of 5dB. The receiver employs a SAW filter at each IF stage for enhanced adjacent channel interface rejection. Two buffered video output signals are provided at BNC connectors, with balanced audio and composite video available on the rugged 10 pin connector. Both NTSC and PAL are available. Low power consumption makes the MR Series ideal for use in remote applications. The optional On Screen Display provides the operator with a visual indication of receiver status on a video overlay by transposing the display over the video signal to aid in tracking airborne transmission systems.
