Analog Devices is aiming at basestations with a phased-locked loop (PLL) synthesiser with integrated voltage-controlled oscillator (VCO). Called ADF4355, typical phase noise is -144dBc/Hz (1MHz offset) at 1.7GHz (typical), integrated jitter is ~150fsrms and the IC operates up to 6.8GHz. “The device’s higher frequency band offers throughput advances for makers of point-to-point microwave links, point-to-multipoint ...
