The BFCQ-2802+ from Mini Circuits is a Bandpass Filter with a passband from 27.5 to 29.5 GHz and a center frequency of 28.4 GHz. It has an insertion loss of less than 3.4 dB in the passband and provides over 20 dB attenuation in the stopband. The filter utilizes a proprietary LTCC material and a distributed filter topology which enables this filter to achieve repeatable performance on a lot-to-lot basis for mmWave frequencies. It is available in a ceramic surface mount package that measures 2.5 × 2.0 mm and is ideal for 5G band n257 telecommunication applications.
