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.
