26_GHz_OSCILLATOR_FOR_RADAR_SPEED_GUN
This circuit consists of 2.6-GHz oscillator Q2, a coupling rrticrostripline to ANT1, a 1.1 1/4 wave probe, detector D2, and audio amp Q1. The oscillator feeds power to the antenna, which radiates the signal. The reflected signal from a moving target mixes with the oscillator signal in D2. The resultant beat note (doppler shift) is amplified by Q1 and fed to jack J1, which is used to feed the circuit 12 Vdc.
