Ultra-broadband downconverters

The DC-0.8/18-70/140/160 and DC-0.5/20-70/140/160-SP are high performance ultra-broadband 2 Hz steps agile downconverters. These downconverters accept RF signals from 0.8-18 GHz and 0.5-20 GHz, respectively, and provide one selectable IF output of either 70, 140 or 160 MHz and one L-band output at 1200 MHz.

The frequency conversion sense of all the outputs can be independently programmed as inverted or non-inverted. Independent gain programming of 42 dB in 1 dB steps is provided for the outputs.

The high quality phase noise makes this system suitable for most applications including the stringent requirements of high order QAM. All system parameters are locally programmable via the front panel keypad or remotely programmable via RS422/RS485/RS232. Front panel rotary knob programming is available for the DC-0.5/20-70/140/160-SP.
