BOARD-BAND LOW-NOISE AMPLIFIER.
Abstract
Research concerned development of broadband, low-noise varactor diode parametric amplifiers. Four engineering breadboards of a low-noise small-signal amplifier were fabricated and tested. The electrical characteristics for one typical unit are: Noise factor, 2.7 db midband 3.5 db band edges; Bandwidth, 1.0 Gc (41%); Center frequency 2.45 Gc; Gain, 18 db = 2 db; Dynamic range, 85 db (1-Mc bandwidth); Satura tion, -20 dbm for 1-db departure from linear operation; and Varactor temperature, room tem perature (290 K). Further improvements in per formance are possible-especially if varactor diodes with greater nonlinearities and lower stray capacitances are used. (Author)
