Integrated Microwave Corp. offers the 928103, a 914.5 MHz ISM bandpass filter. This filter is designed to reject interference to and from adjacent radio services, like the cellular radio band. This high-Q ceramic filter is designed using eight resonators that exhibit high Q (over 1000). The result is a compact filter that handles over 10 W CW, and has low insertion loss (5 dB max) considering its bandwidth.
