PRODUCT OVERVIEW
This is a 3rd order AIS bandpass filter in an enclosure, with excellent sideband rejection. This product is ideally suited for AIS receiver applications at 162 MHz*. In the absence of a bandpass filter, strong signals in adjacent bands such as FM can saturate the receiver. If you would like the same filter without an enclosure go here.
