Combline Bandpass Filter

UBS Combline filter designs incorporate high “Q” structures enabling the realization of high skirt selectivity and very low pass-band insertion loss making them ideally suited for critical receiver front-end or transmitter applications. Increased selectivity is accomplished by the addition of more resonators to the design. The filter housing is generally made from lightweight aluminum and may be silver-plated for improved electrical characteristics. Temperature related frequency shifting is minimized through the use of proprietary design techniques and strict process control. UBS Combline filters are available from 2 to 14 resonator sections with bandwidths up to 30% and operating frequencies from 1GHz to 18 GHz. Please consult our sales department for further details.
