Integrated RF Front-End in 0.13 驴m CMOS for Automotive and Industrial Applications beyond 20 GHz

摘要

An integrated front-end, for automotive and industrial applications beyond 20 GHz, in 0.13mum standard CMOS is presented. The front-end chip includes a low noise amplifier, a transformer-based Gilbert-mixer, an intermediate frequency amplifier and a buffer for the local oscillator input. The differential front-end at 22.5 GHz, measured on test-board, achieves a gain of 25.8 dB, a SSB noise figure of 6.8 dB, an input IP3 of -34.6 dBm and an input 1dB compression point of -41.5 dBm while consuming 112.5 mW at a power supply voltage of 1.5 V
