SA627 Description
The SA627 has faster RSSI rise and fall times. The SA627 is a high performance monolithic low-power FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator (RSSI) with fast rise and fall time, voltage regulator and frequency check/limiter out ( ). The SA627 also has an extra limiter output.
