topGeneral description
The SA607 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 SA607 is available in 20-lead SOL
(surface-mounted miniature package) and 20-lead SSOP package.
The SA607 was designed for portable communication applications and will function down to 2.7V. The RF
section is similar to the famous SA605. The audio output has an internal amplifier with the feedback pin
accessible. The RSSI output is buffered. The SA607 also has an extra limiter output. This signal is buffered
from the output of the limiter and can be used to perform frequency check. This is accomplished by
comparing a reference frequency with the frequency check signal using a comparator to a varactor or PLL at
the oscillator inputs.
