New Cavity Bandpass Filters for STLs

Integrated Microwave is out with a line of ultra-narrow bandpass cavity filters for 900 MHz STL receivers. The company says the cavities were designed as pre-selector filters and offer low loss and steep skirts. They can help resolve signal congestion problems in areas where antenna locations are crowded with transmitters. Typical uses include rejection of other STL signals, paging services and cell phone band noise.
The filter is pretuned to the user’s STL frequency. Ultimate rejection is better than 80 dB. Filters are available for U.S. and Canadian STL bands. Delivery is available in one week; cost is about $500.
