SA604A High-performance low-power FM IF system Rev. 4.3 — 13 July 2016 Product data sheet 1. General description The SA604A is an improved monolithic low-power FM IF system incorporating two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator. The SA604A features higher IF bandwidth (25 MHz) and temperature compensated RSSI and limiters providing wide RSSI dynamic range, high IF/limiter gain and overall stability. The SA604A is available in an SO16 (surface-mounted miniature) and HXQFN16 package. 2. Features and benefits  Low power consumption: 3.3 mA typical  Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a dynamic range in excess of 90 dB  Two audio outputs — muted and un-muted  Low external component count; suitable for crystal/ceramic filters  Excellent sensitivity: 1.5 V across input pins (0.22 V into 50  matching network) for 12 dB SINAD (Signal-to-Noise and Distortion ratio) at 455 kHz  SA604A meets cellular radio specifications 3. Applications  Cellular radio FM IF  High-performance communications receivers  Intermediate frequency amplification and detection up to 25 MHz  RF level meter  Spectrum analyzer  Instrumentation  FSK and ASK data receivers NXP Semiconductors SA604A High-performance low-power FM IF system 4.
