Mini-Circuits’ cavity filters are designed by implementing resonant structures with very high Q and are ideal for
narrow-band, high-selectivity applications. These designs can provide bandwidths as narrow as 1% with very high
selectivity and excellent low noise floor. Low insertion loss combined with excellent power handling makes them
well-suited for transmitter and receiver front end. Advanced filter design and construction enables stopband width
greater than 3x the center frequency.
Mini-Circuits’ cavity filters feature a special protective assembly to prevent accidental de-tuning that would otherwise require expensive replacement or return to factory for re-tuning. Custom integrated assembly with LNA and
bias tees results in greatly simplifying system integration . Precise machining allows realization of cavity filters with
small form factors for applications where size is critical. Excellent repeatability across units is achieved through
precise tuning and process control.
