Abstract :
A monolithic vector modulator element has been demonstrated that combines the biphase modulation and gain control functions on a single chip covering the 0.3- to 3-GHz frequency band. Over 50 dB of gain control is provided. The implementation and the MMIC (monolithic microwave integrated circuit) description are presented, and the RF performance is discussed.<>
