2089-24 Downconverter, 2.0-2.4 GHz

  
The Series 2089-24 Downconverter converts 2.0 - 2.4 GHz to a 70 MHz IF with no spectrum inversion, high linearity, good phase noise, flat frequency response, and 1 MHz tuning steps. The 2.0 - 2.4 GHz input is mixed with synthesized local oscillator (LO) signals, first to 900 MHz and finally to 70 MHz IF. Front panel LEDs indicate DC power is applied (green) and if a PLL alarm occurs (red). The gain is set at 10 dB . Connectors are type N female for the RF input and BNC female for the IF output. The 2089-24 is housed in an 1 3/4” X 19 “ X 14 “ deep rack mount chassis.
