Low noise C-band amplifier

The results of design of low noise amplifier for C-band satcom stations are presented. 40 K of noise temperature and more than 60 dB gain have been obtained in 500 MHz bandwidth with WSVR less than 1.2. The amplifier includes four stages: amplifier, DC linear controller of supply voltage, low noise regulated GaAs FET bias and matching circuits. Minimal number of construction units ensures high reliability and low cost of serial production.
