SA604AD中文资料High performance low power FM IF system数据手册恩XP规格书

描述 Description

The SA604A is an improved monolithic low-power FM IF system incorporating two limitingintermediate frequency amplifiers, quadrature detector, muting, logarithmic receivedsignal strength indicator, and voltage regulator. The SA604A features higher IF bandwidth(25 MHz) and temperature compensated RSSI and limiters providing wide RSSI dynamicrange, high IF/limiter gain and overall stability. The SA604A is available in an SO16(surface-mounted miniature) and HXQFN16 package.

特性 Features

• Low power consumption: 3.3 mA typical
• Temperature compensated logarithmic Received Signal Strength Indicator (RSSI) witha 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 μV across input pins (0.22 μV into 50 Ω matching network) for12 dB SINAD (Signal-to-Noise and Distortion ratio) at 455 kHz
• SA604A meets cellular radio specifications
Target Applications
• Cellular radio FM IF
• High-performance communications receivers
