RF Filter Solutions
We primarily focus on large programs and therefore our RF filter solutions are custom-designed to meet your requirements. You can send your requirements to a member of our sales team, or you can use our Specify a Filter tool to submit your requirements. Our engineering team will work with you to provide the right filter topology supported by simulation data. The products listed below represent the wide variety of filter topologies we can employ.
Bandpass filters
Lowpass filters
Band reject filters
Highpass filters
Utilizing sophisticated software such as Sonnet EM Simulator and SolidWorks, creative layouts can be realized to optimize package size and electrical performance.
To optimize rejection and minimize loss, Spectrum Control engineers blend multiple topologies into a single small housing.
Careful analysis of current densities and heat dissipation allow for higher power handling and smaller package size.
Lowpass, Highpass and Bandpass filters can be combined to form our state-of-the-art Diplexers, Triplexers and Multiplexers. Spectrum Control utilizes Suspended Substrate, Lumped Element, Ceramic, Waveguide, and Cavity filters in our Multiplexer (MUX) designs.
