Design of Ka-band Transceiver for Satellite Communication

This paper presents the design of Ka-band low-power transceiver. Due to the rapid development of the Internet of Thing (IoT), the strong demand for low power wireless communication system is growing day by day. With the rapid progress of CMOS technology, the cutoff frequency of transistor is greatly increased. There are many new opportunities for CMOS in RF circuits. However, it's still a challenging mission to realized low-power consumption and high-performance CMOS RF circuits. This paper tried to use the standard 0.18-μm CMOS process with a compact chip size to realize the LNA/driver amplifier/frequency converter/phase shifter for Ka-band satellite communications. The final output stage is using GaAs p-HEMT for high power amplifier.
