NXP | SA604AD/01,118

The SA604AD/01,118 is a Part of SA604A Series 25 MHz High performance low power FM IF System.Operating temperature ranges from -40°C to 85°C and is available in surface mount SOIC-16 Package.

The SA604A FM IF system incorporates two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator, and voltage regulator.

Features:

• Low power consumption: 3.3mA typical
• Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) with a dynamic range in excess of 90dB
• Two audio outputs - muted and unmuted
• Low external component count: suitable for crystal/ceramic filters
• Excellent sensitivity: 1.5 µV across input pins (0.22 µV into 50 Ω matching network) for 12dB SINAD (Signal to Noise and Distortion ratio) at 455kHz
• SA604A meets cellular radio specifications

Applications:

• Cellular radio FM IF
• High performance communications receivers
• Intermediate frequency amplification and detection up to 25MHz
• RF level meter
• Spectrum analyzer
• Instrumentation
• FSK and ASK data receivers
