DEVELOPMENT OF A LARGE DYNAMIC RANGE TUNNEL DIODE AMPLIFIER FOR PHASED ARRAY RECEIVERS

Abstract

An investigation was made to develop large dynamic range S-band tunnel diode amplifiers for phased array receivers. The report covers a reproducibility study of these amplifiers, and the investigation of amplifier characteristics pertinent to phased array applications. Three two-stage tunnel diode amplifiers were delivered to Lincoln Laboratory. These amplifiers operate at a center frequency of 2.85Gc/s =2%, have a 1.5dB bandwidth ranging from 400- 450 Mc/s at a gain of 18.0 to 18.5 dB, and have a noise figure between 5.6 and 5.9 dB. The amplifiers are unconditionally stable, and their output power at the 1 dB compression point ranges from - 10.5 dBm to - 12 dBm. The phases of any two amplifiers track within =3 degrees over a band of 110-190 Mc/s, and the amplitudes track within =1/2 dB over a Band of 290-410 Mc/s.
