This device is designed to generate a quadrature local oscillator signal. A quadrature generator circuit constructed in CMOS logic and consists of two converters ECL/CMOS, quadrature former with input frequency divider by 2 or 4, prescaler by 2, 4, 8, 16 and phase control block, with ability of fine tuning of output signal phase. To reduce phase noise output triggers are strobbed by high-frequency signal.
