DESCRIPTION
The SA607 is a low voltage high performance monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA607 is available in 20-lead SOL (surface-mounted miniature package) and 20-lead SSOP package.

FEATURES
• Low power consumption: 3.5mA typical at 3V
• Mixer input to >150MHz
• Mixer conversion power gain of 17dB at 45MHz
• XTAL oscillator effective to 150MHz (L.C. oscillator or external
    oscillator can be used at higher frequencies)
• 102dB of IF Amp/Limiter gain
• 2MHz limiter small signal bandwidth
• Temperature compensated logarithmic Received Signal Strength
    Indicator (RSSI) with a 90dB dynamic range
• Low external component count; suitable for crystal/ceramic/LC
    filters
• Excellent sensitivity: 0.31µV into 50Ω matching network for 12dB
    SINAD (Signal to Noise and Distortion ratio) for 1kHz tone, 8kHz
    deviation with RF at 45MHz and IF at 455kHz
