board demo RF/IF sa614ahr

SA614A
Low power FM IF system
Rev. 4 — 14 February 2014
Product data sheet
1. General description
The SA614A is an improved monolithic low-power FM IF system. It incorporates two
limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic
received signal strength indicator, and voltage regulator. The SA614A features higher IF
bandwidth (25 MHz) and temperature compensated RSSI and limiters permitting higher
performance application compared with the SA604. The SA614A is available in a SO
(surface-mounted miniature) package.
2. Features and benefits
Low power consumption: 3.3 mA typical
Temperature compensated logarithmic RSSI with a 90 dB dynamic range
Two audio outputs - muted and unmuted
Low external component count; suitable for crystal/ceramic filters
Excellent sensitivity: 1.5
V
across inputs pins (0.22
V
into 50
matching network)
for 12 dB SINAD (SIgnal-to-Noise-And-Distortion ratio) for 1 kHz tone with RF at
45 MHz and IF at 455 kHz
SA614A meets cellular radio specifications
3. Applications
Cellular radio FM IF
High performance communication receiver
Intermediate frequency amplification and detection up to 25 MHz
RF level meter
Spectrum analyzer
Instrumentation
FSK and ASK data receivers
