SA647 Description
The SA647 is a low-voltage high performance monolithic digital system with high-speed RSSI incorporating a mixer, oscillator with buffered output, two limiting intermediate frequency amplifiers, fast logarithmic received signal strength indicator (RSSI), voltage regulator, RSSI op amp and power down pin. The SA647 is available in TSSOP (thin shrink small outline package). The SA647 was designed for portable digital...
