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.
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 µV across input pins (0.22 µV into 50 Ω 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
Target Applications
Cellular radio FM IF
High performance communications receivers
Intermediate frequency amplification and detection up to 25MHz
