Abstract :
On low altitude radar system heavy reflective clutter from earth case saturation receiver amplifier, for stoppage receiver saturation using a crystal notch filter on input of IF stage Crystal filter having high Q and selective frequency and band width, they have high resistance for changing temperature so this filter suitable for radar receiver. In this paper we try to showing suitable method for increase Q and selective width of filter band width, to design a filter can attenuation 60dB selective band width of receiver by selective frequency. On crystal notch filter using trans for increasing circuit impedance and filter band width.
