This product consists of an RF input amplifier, Gilbert cell mixer, Local Oscillator or LO buffer, IF amplifier, external filter port, and IF output limiting amplifier. The on-chip local oscillator only requires an external tank circuit. The power save feature enables users to minimize overall current consumption when dormant. This device was specifically designed for low-cost second IF receivers, keyless entry applications, security systems, GPS, and other low power Part 15 mobile radios.
