This study presents a CMOS 1-channel beamforming front-end IC for 6G upper midband communications. The proposed chip consists of a variable gain phase shifter (VGPS) for gain and phase control and a power amplifier (PA) for high output power. The VGPS consists of an IQ generator, two vector generators, and a vector-summing circuit. The chip is fabricated using a 65-nm CMOS process, and its core area, excluding the pads, was 0.79 mm². To achieve a high linear output power, a cold-FET-based linearizer is implemented in the drive stage. The proposed 1-channel beamforming chip achieved a gain of 26.8 dB, P1dB of 23 dBm, rms phase error of 0.8°, AM-AM distortion of 0.9 dB, and AM-PM distortion of 1.7° at 15.1 GHz. The 3 dB bandwidth ranges from 14.1 to 18.2 GHz.
