Wideband PA and LAN for 60-GHz Radio in 90-nm LP CMOS Technology

paper reports a LNA and a PA for IEEE802.15 WAPN application in a 90-nm LP (low power) 1P6M CMOS technology. The LNA has a 13-dB peak gain and a 7-dB NF and the PA has a 9.8-dB gain and a +11.2-dBm saturated output power. Both LNA and PA have achieved input and output matching bandwidths exceeding 10 GHz, while the reflection coefficient (|S
₁₁
|, |S
₂₂
|) < -10 dB. The design was targeted that |S
₂₂
| variation within 2 dB from the peak over the frequencies and the measured 2-dB bandwidth of both LNA and PA are also exceeding 14 GHz. Both LAN and PA should be able to accommodate 9-GHz bandwidth requirement of IEEE802.15 WPAN application. A high performance PA and LNA are achieved with this backend process.
