Abstract :
The paper presents the results of designing microwave monolithic integrated circuit of two-stage amplifier produced on pHEMT substrate with chip size 2.4×1.6 mm2 and providing 16.5 dB conversion gain and 15 dBm P1dB on 2.0-6.0 GHz. The method of MMIC multistage amplifier designing is developed. FET topology has been optimized for minimization of parasitic parameters and maximization of dynamic range. GaAs pHEMT MMIC two-stage amplifiers are developed and manufactured by using MESFET with 0.7 μm gate´s length as an active element. Characteristics of the device are investigated experimentally in 2.0-6.0 GHz frequency range. Results of measurements are agreed with calculation data and confirm effectiveness of the developed method of designing.
