Abstract
This letter presents a 27-32 GHz compact phase shifter (PS) and attenuator (ATT) in 16-element phased-array for satellite communication (SATCOM) in 65-nm CMOS technology. Each element comprises a 5-bit switched-type attenuator (STA), a driver amplifier (DA), a 6-bit vector modulation phase shifter (VMPS) and a two-stage power amplifier (PA). STA occupies an area of only 60 μm × 100 μm, enabled by capacitive compensation technology. Furthermore, an extremely compact layout of the I/Q signal generation reduces the VMPS area to 140 μm × 225 μm.Keywords
