SA58641 - NXP

SA58641 High performance mixer FM-IF

The SA58641 is a high performance monolithic FM IF system with high-speed RSSI incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic Received Signal Strength Indicator (RSSI), voltage regulator, wideband data output and fast RSSI op amps. The SA58641 is available in 20-lead SSOP (Shrink Small Outli.
