The SA605 is a high performance low power mixer FM IF system with features including mixer/oscillator, limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator (RSSI), and voltage regulator.
The SA605 is a monolithic FM IF system that combines a mixer/oscillator, two limiting IF amplifiers, a quadrature detector, muting, a logarithmic RSSI and a voltage regulator. It targets cellular radio, high‑performance communications receivers, single‑conversion VHF/UHF receivers and other RF applications.
The device is offered in 20‑lead DIP, SOL and SSOP packages and operates from a 6 V supply with typical 5.7 mA current draw. Key features include a 13 dB mixer conversion gain at 45 MHz, 4.6 dB noise figure, 25 MHz IF bandwidth and temperature‑compensated RSSI with over 90 dB dynamic range.
