Abstract :
This paper proposes a circuit topology to reduce the size of a single-pole-double-throw (SPDT) quarter-wavelength band-pass filter-integrated switch (FIS). A low loss Q-band reduced-size MMIC SPDT FIS is developed in a 0.15-μm MHEMT process. This circuit demonstrates a measured insertion loss of lower than 1 dB, isolation of greater than 35 dB, and return losses of greater than 12 dB from 30 to 50 GHz, with a chip size of 2 mm x 1 mm. The low insertion loss, high return loss and isolation show that performance is improved when reducing the chip size of the circuit.
