Abstract :
A voltage-controlled phase-shift network is presented in which a continuous change in phase of up to 60 deg per section may be obtained at constant impedance in the h.f. and v.h.f. range. Theoretical and experimental results are compared for two typical circuits, operating at 1 Mc/s and 80 Mc/s, which have an insertion loss of less than 1 dB, and a bandwidth of about 10%.
