Abstract :
A bandpass filter with a centre frequency of 750 MHz and a bandwidth of 52 MHz is described. The filter consists of 5 parallel-coupled microstrip sections realised on a barium tetratitanate substrate (¿r = 37). A flat passband and high-attenuation stopbands are obtained. The measured response agrees with theoretical predictions.
