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.
