This article presents a design approach of a band-pass filter which is fabricated on an integrated passive device process and is capable of operating over the unlicensed 60-GHz band (57-64 GHz). The band-pass filter proposed in this article evolves from a typical one comprising two identical, mirrored open-loop half-wavelength microstrip line resonators. The experimental results demonstrate an insertion loss of less than 2.4 dB, a return loss of better than 10 dB over the 60-GHz band, and a 3-dB bandwidth of 24 GHz (∼42%). The simulation and measurement results are well matched up to 110 GHz. This filter is suited for system-in-a-package V-band front-end systems.
