Reflection mode filtering methods are implemented with dual hairpin resonator networks, using the inherent parasitic losses in the resonators to create matched loads at the stopband frequencies of interest while reflecting passband power. Notches of 6 dB and 10.6 dB stopband insertion loss, and 3.7% and 5.6% relative bandwidths respectively, were achieved. This represents the first implementation of reflection mode filtering in the W-band on-chip.en© The Institution of Engineering and Technology 2016.
