Bandpass Filter 100MHz - 70GHz RF Cavity Filter Microwave Filter
Cavity filter, using the basic electromagnetic resonance cavity principle, can achieve frequency bands including P, L, S, C, X, KU, K, KA, Q, U, W and other bands, with low insertion loss, excellent out-of-band suppression, Compact structure, harmonic suppression, high power capacity, etc. The Q value is high, the performance index is excellent, and the cost performance is relatively high. Among them, the cavity band rejection filter is an irreplaceable device in a mobile communication test system. Cavity filters are also widely used in military and civilian applications such as satellite communications, test and measurement, and electronic countermeasures.
