Summary
JT-QTF-1268-MCX-1 cavity filter is a bandpass filter used to select signal frequency bands, limit input signal bandwidth, suppress noise, and improve signal to noise ratio.
Mainly used in military Beidou navigation and communication systems, and can also be used in civilian Beidou navigation and communication subsystems.
Characteristic
Small size, light weight, strong environmental adaptability, and high reliability.
