NE604A中文资料High performance low power FM IF system数据手册恩XP规格书

描述 Description

DESCRIPTION
The NE/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 NE/SA604A features higher IF bandwidth (25MHz) and temperature compensated RSSI and limiters permitting higher performance application compared with the NE/SA604. The NE/SA604A is available in a 16-lead dual-in-line plastic and 16-lead SO (surface-mounted miniature) package.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: 1.5µV across input pins (0.22µV into 50Ω matching network) for 12dB SINAD (Signal to Noise and Distortion ratio) at 455kHz
• SA604A meets cellular radio specificationsAPPLICATIONS
• 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
