W-band microshield low-pass filters Conference Paper uri icon


  • Experimental and theoretical results are presented for a planar W-Band low-pass filter. A stepped impedance implementation of a 7-section 0.5 dB equal ripple Chebyshev filter achieves an insertion loss of 1 dB in the passband and a 90 GHz cutoff frequency. The filter is fabricated in microshield line technology, a new type of planar transmission line based on coplanar waveguide supported by a thin dielectric membrane. The inadequacy of conventional quasi-static models is discussed, and a Finite-Difference Time-Domain (FDTD) analysis is applied to predict the filter performance.<>
