Progress is reported on work to develop an experimental model of an electronically tunable receiver operating between 300 and 3000 mc with a sensitivity of -90 dbm and high dynamic range. The essentially solid state design basically consists of a low-pass input filter, upconverter and associated X-band sweeper, bandpass filter, tunneldiode amplifier, downconverter, and i -f amplifier-detector. Advances in tunnel-diode amplifier technology have precluded the need for an originally planned saturation-control circuit. Author
