Four channel 60 GHz upconversion mixer with 14 dB gain and 2.5 dBm P1dB using tr

A 60 GHz upconversion mixer is realised in a 65 nm LP CMOS. The mixer consists of a Gilbert cell, a LO buffer and a RF buffer. To enhance the bandwidth and reduce the area, the transformer impedance matching network is used. The measured results show that the mixer covers the IEEE 802.15.3c standard
