DESCRIPTION

The SA616 is a low-voltage high performance monolithic FM IF

system incorporating a mixer/oscillator, two limiting intermediate

frequency amplifiers, quadrature detector, logarithmic received

signal strength indicator (RSSI), voltage regulator and audio and

RSSI op amps. The SA616 is available in 20-lead SSOP (shrink

small outline package).

The SA616 was designed for portable communication applications

and will function down to 2.7V. The RF section is similar to the

famous SA615. The audio and RSSI outputs have amplifiers with

access to the feedback path. This enables the designer to adjust

the output levels or add filtering.

FEATURES

oscillator can be used at higher frequencies)

Indicator (RSSI) with a 80dB dynamic range

filters

SINAD (Signal to Noise and Distortion ratio) for 1kHz tone with RF

at 45MHz and IF at 455kHz
