Integrated Microwave offers exceptionally narrowband cavity filters for STL bands around the world. Any STL receiver can benefit from the use of a preselector filter. STL filters offer outstanding signal separation without compromising signal strength or noise figure. Passband loss is typically 9 db, while rejection is over 80 dbc. These filters allow virtually private frequency use in congested areas. All filters come pretuned to your STL frequency and STL bandwidth, and can be returned at the factory for future frequencies. These filters are designed for indoor use. Let Integrated Microwave's 30 years of experience work for you.
These spectrum analyzer plots were provided by KFMB Radio in San Diego. Photos A and B display the STL band as seen from their transmitting facility on Mount Soledad, La Jolla. Their STL frequency is exactly center-screen. In photos C and D you can see the same spectrum viewed through our 600 kHz bandwidth STL filter.
