When a bandpass filter
will not provide enough isolation from close-in narrowband
single carriers (e.g. – adjacent FM channel), consider
removing that carrier with a notch filter.
MFC’s tunable notch
filters are available in single (selective), double (highly-selective)
& triple (ultra-selective) cavity arrays. Choose from the
(6) models that cover the bands between (22-900) MHz.
…..and for applications between (900-1450) MHz, we offer
similar narrow notch filters
that are cut to your specified frequency.
For more robust electrical performance and power handling capabilities,
we offer larger (quarter-wave design) high
“Q” cavity notch filters and high
“Q” cavity bandpass filters.
