Abstract
A circuit was developed which permits variable attenuation of an RF signal containing Doppler information while holding the phase shift of the signal to a minimum. A phase shift change of less than 2° was achieved for a 50-dB dynamic range. The design is centered around a p-i-n diode as the control element.
