2016-25 Downconverter, 2200 to 2500 MHz

  
The 2016-25 Downconverter converts 2200 to 2500 MHz to 70 ± 18 MHz in 1 MHz steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-function push button switches select the RF frequency and gain. Front panel LEDs provide indication of DC power (green) and PLL alarm (red). Variable attenuators for the RF input provide a gain range of 0 to +50 dB as adjusted by the front panel multi-function pushbutton switches. Frequency and gain settings appear on the LCD display. Connectors are BNC female for RF and IF signals. Powered by a 90-260 VAC power supply; 1 3/4” X 19 “ X 16” rack mount chassis.
