Overview
The SA636BS,115 is a low-voltage, high-performance monolithic FM IF (Intermediate Frequency) system designed by NXP USA Inc. This component is particularly suited for high bandwidth portable communication applications. It integrates a mixer/oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, a logarithmic Received Signal Strength Indicator (RSSI), a voltage regulator, and wideband data output. The SA636BS,115 operates effectively down to 2.7 V and is available in both 20-lead SSOP (Shrink Small Outline Package) and HVQFN20 (quad flat package) configurations.
