FDC101 is a high dynamic range frequency converter that downgrades signals in the 100 MHz to 18 GHz frequency range into three user-selectable intermediate frequencies (IFs): 70 MHz, 140 MHz and 160 MHz. In addition to three IF outputs, it provides one L-band output at 1 GHz. The real-time bandwidth at the L-band output is 500 MHz. There are 8 selectable sharp filters on the 70 MHz and 160 MHz IF outputs. Both IF and L-Band outputs can be viewed from the monitor outputs located on the rear panel. The outputs of the local oscillators in the device can be accessed from the rear panel optionally.

The technical specifications of the FDC101 are such that it meets the need for a high performance microwave ELINT receiver. The FDC101 is designed to detect high data rate PCM/TDM signals and RADAR signals that require high pulse accuracy. With its low group latency decay and ultra-low phase noise, the FDC101 allows the detection of modern digital modulated signals such as high-level QAM.
