A Ku Band (15∼18 GHz) 4-Element (4 Transmitters/4 Receivers) fully differential phased array transceiver is designed and fabricated using a 180nm CMOS process. The proposed phased array integrated with T/R switches and SPI controller is based on an all-RF structure. TX and RX channels are placed side-by-side to improve integration density and isolation. Each channel consists of a 5-bit phase shifter...
This paper presents the design of a Ku-band CMOS low noise amplifier (LNA) with noise reduction and gain improvement. A transformer feedforward gm-boosting technique is employed in a single-ended common-gate LNA to reduce the noise figure (NF) and improve the gain simultaneously. A single cascode is the second stage of the LNA. Fabricated in 0.18um RF CMOS process, the LNA exhibits a minimum noise...
