Abstract

This paper presents a 0.18um CMOS Ku-band 6-bit phase shifter for phased array transceiver applications. Design specifications of proposed phase shifter are less than 2.5o RMS phase error (less than half LSB) in 15.3 GHz to 18.3 GHz frequency band (16.8 GHz center frequency) and less than 12 dB insertion loss for phased array aplications.
Phase shifter blocks are designed in high - pass and low - pass topology and ADS software has been used for conducting electromagnetic simulations. Designed phase shifter has been fabricated in 180nm TSMC process and measured. There is excellent matching between simulation and measured results.
