The SA615 is a monolithic low-power FM IF system that incorporates a mixer/oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, muting, a logarithmic received signal strength indicator (RSSI), and a voltage regulator. It is designed for high-performance applications such as cellular radio FM IF, high-performance communications receivers, and single conversion VHF/UHF receivers.
