The effect of substrate/package width on filter performance is demonstrated and discussed for 18‐GHz packaged filters using high‐temperature superconducting (HTS), coupled microstrip lines. The filters are made of 0.3‐μm YBa 2 Cu 3 O 7 – ∂8 (YBCO) on MgO substrates with copper ground planes. The HTS filter shows a minimum insertion loss (IL) of 0.9 dB, steep skirts, and very good out‐of‐band rejection (> 45 dB up to 21 GHz) at 77 K with a bandwidth of 2.8% and a 0.3‐dB ripple. © 1995 John Wiley & Sons, Inc.
