Abstract:
This article presents an eight-channel dual-polarized Ku-band transmitter (Tx) beamformer integrated circuit (BFIC) fabricated in a 22-nm GlobalFoundries FDSOI process. Each channel integrates independent phase and gain control utilizing a 7-bit active phase shifter (PS) and a 5.5-bit attenuator (ATT). To mitigate performance degradation caused by load impedance variations in …
