Abstract :
The authors describe the design of a 4-bit phase shifter GaAs MMIC for operation over a 4-8 GHz bandwidth. Phase shifting is achieved by using GaAs MESFETs to switch the circuit transfer function from high pass to low pass and vice versa. In order to achieve small chip size and improved phase accuracy a novel component has been developed
