An on-chip implementation of a W-band filter with dual notches at 82
GHz and 95 GHz is presented. 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.
