Abstract

We present an integrated frequency synthesizer in 65nm CMOS to enable the 81-86GHz satellite communication transceiver. The frequency synthesizer is inserted in a two-step zero-IF millimeter-wave transceiver with LORF at 70-78GHz and LOIF at 1/8 of LORF to cover the desired entire frequency bands. It also features coarse phase rotation to endow beam forming capabilities for the intended communication system. The phase noise is < -83dBc/Hz at 1MHz offset as extrapolated from measured value at 1/8 of the VCO frequency (∼9.4GHz). The measured reference spur is <-49dBc. Total synthesizer power consumption including LO buffers and phase rotators is 65mW at 1V power supply and the compact layout has rendered small synthesizer core area of 0.16mm2.
