Description

The SA636 is a low-voltage 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 ic is available in 20-lead SSOP (Shrink Small Outline Package) and HVQFN20 (quad flat package).

A Mixer FM IF (Intermediate Frequency) system is a circuit used in radio communication and broadcasting systems to convert the frequency of an incoming signal to a fixed intermediate frequency for further processing. It is commonly used in FM (Frequency Modulation) radios and receivers.

The mixer FM IF system is a critical component of FM radios and receivers, allowing for the efficient conversion and processing of incoming signals to produce high-quality audio output.

Features

1. Wideband data output (600 kHz minimum)

2. Fast RSSI rise and fall times

3. Low power consumption: 6.5 mA typical at 3 V

4. Mixer input to >500 MHz

5. Mixer conversion power gain of 11 dB at 240 MHz
