CAVITY FILTERS


Cavity Filters are known for low insertion loss and higher power handling ability. API Technologies engineers researched the suppression of intermodulation products in low loss, high power cavity designs and through careful process control and component selection devised specialized design techniques to satisfy our customers’ unique requirements.

Superior pseudo-elliptic designs our engineers generate reduce the number of sections required to meet a specified attenuation response, thereby generating a smaller cavity filter with lower passband loss, and reduced costs. Similar techniques may be employed to provide passband group delay equalization or increase attenuation over a specified stopband region.
