A MMIC 4.3-GHz tunable low-pass filter

A microwave integrated, tunable, low‐pass filter is presented. This coplanar filter exhibits a wide tuning range of the cutoff frequency (±19% around 4.3 GHz) and a −30 dB stopband that extends up to 30 GHz. Insertion loss is 1.5 dB at low frequencies and return loss is better than 14 dB in the pass...

Summary:A microwave integrated, tunable, low‐pass filter is presented. This coplanar filter exhibits a wide tuning range of the cutoff frequency (±19% around 4.3 GHz) and a −30 dB stopband that extends up to 30 GHz. Insertion loss is 1.5 dB at low frequencies and return loss is better than 14 dB in the passband. © 2008 Wiley Periodicals, Inc.
