A compact 60‐GHz on‐chip bandpass filter in GaAs technology
Electronics Letters, Volume 60, Issue 7, April 2024.A compact 60‐GHz on‐chip bandpass filter (BPF) is presented using gallium arsenide (GaAs) technology. The measurements show that it has a centre frequency of 60.2 GHz with a bandwidth of 14%, and the minimum insertion loss (IL) within the passband is 2.57 dB. The chip size, excluding the feedings, is about 0.265 mm × 0.184 mm. Abstract A compact 60‐GHz
