Integrated Microwave offers wide and narrowband cavity filters for Canadian and US STL bands. These filters are designed for receiver preselector use, offering outstanding signal separation without compromising signal strength or noise figure. Passband loss is typically 4 db or less, while rejection is over 80 dbc. These filters allow virtually private band use in congested areas. Wideband filters cover 100% of the STL band, while narrowband versions can be less than 750 kHz wide. All filters come pretuned to your STL frequency and STL bandwidth, and can be retuned at the factory for future frequencies. These rugged filters are for indoor use. Outdoor versions are available. Let Integrated Microwave's 20 years of experience work for you. When space permits, IMC cavity filters provide near-perfect filtering solutions for under $500.

These spectrum analyzer plots were provided by KFMB Radio in San Diego. The display above is the STL band as seen from their transmitting facility on Mount Soledad, La Jolla. Their STL frequency is exactly center-screen. Below you can see the same spectrum viewed through our 1 mHz bandwidth STL filter.
