Dielectric Resonator Bandpass Filter
High performance Dielectric Resonator band-pass filter is based on coupled cavities design and has exceptional performance characteristics. Key quality is its ability to provide significant out-of-band attenuation in very close proximity of the filter’s pass-band, while providing a low loss path to the transmit signal.
The Output Filter is robust and compact. The High-Q values of the ceramic materials permit the use of small cavity structures keeping the weight and size of the filter to a minimum. The ceramic materials are also very stable in relationship to temperature resulting in minimal frequency shifting over a broad temperature range.
