  Lumped Element Filters: provide various filter functions in relatively small packages. They are ideal for rugged environments such as airborne military applications and space. LumpElement4

 

cavityFilter4

 

Cavity Filters: ideal for narrow band applications which require low insertion loss and/or high power handling.  
  Tubular/Coaxial Filters: offer high rejection levels and broad stopbands. They are ideal for high power applications such as reducing harmonics of amplifiers. tubular5

 

ceramicfilter

 

Ceramic Filters: offer an insertion loss that is less than an equivalent lumped element filter with a package size that is smaller than an equivalent cavity filter.  
  Diplexers, Triplexers, Multiplexers: Lowpass, Highpass and Bandpass filters can be combined to form our state-of-the-art Diplexers, Triplexers and Multiplexers. APITech utilizes Suspended Substrate, Lumped Element, Ceramic, Waveguide, and Cavity filters in our Multiplexer (MUX) designs. plexfilter2
