A high-Q bandpass biquad filter operating at 18GHz is proposed. It is based on an active parallel resonator and it is suitable for MMIC implementation. A prototype has been implement ed using the Philips ED02AH PHEMT foundry process. A quality factor of 120 at 18GHz with a current consumption of 5mA @ 2V bias has been reported.
