To evaluate various Air Force receivers and transmitters in a satellite communications application, it is necessary to convert their operating frequencies within the capabilities of the K-Band Terminal Simulator portion of CSEL. This report describes four frequency converters provided for this purpose. Each includes a local oscillator with a stability of 2 x 10 to the minus 8th power per day so that the frequency drift should be negligible and, in addition, each converter uses dual conversion so that the output signal is not inverted when compared to the input signal. Two converters are provided which covert input signals of 700 MHz to 560 MHz and the remaining two convert 367.5 MHz to 700 MHz and 367.5 MHz to 560 MHz. Input and output levels can be as high as 0 DBm except for the 367.5 to 560 MHz converter, which will accept input signals as high as 30 dBm 1 watt.
