Product details

Description

The SA58640 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic RSSI, voltage regulator and audio and RSSI operational amplifiers.

Features

Low power consumption: 5.0 mA typical at 5 V.
Mixer input to >100 MHz.
Mixer conversion power gain of 17 dB at 45 MHz.
Crystal oscillator effective to 100 MHz (LC oscillator or external oscillator can be used at higher frequencies).
102 dB of IF amplifier/limiter gain.
2 MHz IF amplifier/limiter small signal bandwidth.
Temperature compensated logarithmic RSSI with a 70 dB dynamic range.
Low external component count; suitabl.
