Resonator

Resonator Function: combing resonator of filter with cavity and resonance cover so that the electromagnetic field can cause resonance at special frequency and form energy transformation and frequency conversion. Features: The precision of this product is high, the surface quality of which is good and it is helpful to stabilize manufacture process of filter, promote filter insertion loss, inter-modulation and other main performances; the insertion loss is small and the inter- modulation performance is excellent; the low expansion coefficient materials are used and special process treatment is handled in order to ensure stability of resonant frequency at extreme environment)
