UHF Frequency Converter used in EP7/51l to produce local

oscillator power for C02/535. Accepts input from C02/535

via FL2/533 or FL2/534 and mixes it with an internally

generated oscillation to provide the required frequency.

Inputs and outputs may be in Bands IV or V. Printed

circuit board. DD 1967. OBSOLESCENT.
