Miteq Model 6107 Range Calibration Subsystem 70 MHz Satcom RF 19" 2U Rack

Miteq Model 6107 Range Calibration Subsystem 70 MHz Satcom RF 19" 2U Rack

The Miteq Model 6107 is a 19-inch 2U rackmount Range Calibration Subsystem operating at 70 MHz, designed for use in satellite communications (satcom) ground station and microwave RF test environments. Built by Miteq Inc. of Hauppauge, New York, it integrates multiple RF signal processing and audio modules into a single self-contained chassis for range calibration and test functions. The front panel provides FM Demodulator and Phase Modulator output level controls, a Summary Status LED, voltage test points (+15V, -15V, +5V, GND), and a push-button power switch.

Applications

The Miteq 6107 Range Calibration Subsystem is the type of integrated RF chassis used in satellite ground station test ranges and telemetry tracking stations, where a 70 MHz intermediate frequency (IF) signal path is standard for uplink/downlink signal processing and calibration. Systems like this were widely used from the 1970s through the 1990s in government, military, and commercial satcom facilities — including range instrumentation systems for tracking rockets, missiles, and spacecraft. The 70 MHz IF is the classic satcom IF frequency used with L-band and C-band frequency converters, making this type of subsystem compatible with a broad range of ground terminal equipment. The integrated FM demodulation, phase modulation, automatic gain control (AGC), baseband signal routing, and audio processing modules allow a range station to perform end-to-end link calibration and signal verification in a single racked unit. This class of equipment is still relevant today for legacy satcom ground station maintenance, range instrumentation test benches, and RF lab calibration work.
