Overview
The SA612AD/01,112 is a low-power VHF monolithic double-balanced mixer produced by NXP USA Inc. It is designed for low-cost, low-power communication systems and features an on-board oscillator and voltage regulator. This component is particularly suited for applications requiring signal frequencies up to 500 MHz and local oscillator frequencies as high as 200 MHz. The SA612A uses a Gilbert cell multiplier configuration, providing a gain of 14 dB or more at 45 MHz and a noise figure typically below 6 dB, making it ideal for high-performance cordless phones, cellular radios, and other battery-operated equipment.
