Design and auto-screening of a K-Band GaAs MMIC multi-function power amplifier
چکیده انگلیسی


• A novel K-band multi-function power amplifier (MFPA) is proposed.
• It has a centre operation frequency at 22.5 GHz with 1 GHz bandwidth.
• Its linear gain is greater than 21 dB.
• 19 dB power gain and over 40% power added efficiency (PAE) at 2 dB compress point with 0 dBm input power.
• An automatic test and screen software is developed for the test of MFPA.

This paper introduces the design and auto-screening of a K-band multi-function power amplifier (MFPA). The proposed MFPA is fabricated using 0.25 μm GaAs pHEMT technology and has a center operation frequency at 22.5 GHz with 1 GHz bandwidth. It consists of three ports: Transmission port, Receiving port and Common port. The transmission channel which starts from Transmission port and ends at Common port provides a linear gain greater than 21 dB, a 19 dB power gain and over 40% power added efficiency (PAE) at 2 dB compress point with 0 dBm input power. The receiving channel, from Common port to Receiving port, has an insertion loss of less than 1.3 dB. The isolation between the transmission channel and the receiving channel is better than 20 dBc. A piece of auto-screening software is presented here as well to characterize and screen the designed MFPA which is able to accelerate the test three times faster.
