The Philips NE/SA604A is an improved monolithic low-power FM IF system designed for high-performance applications such as cellular radio and communications receivers. It incorporates two limiting intermediate frequency amplifiers, a quadrature detector, muting, a logarithmic received signal strength indicator (RSSI), and a voltage regulator. The device offers a higher IF bandwidth of 25MHz and temperature-compensated RSSI compared to the NE/SA604.
| DC current drain | 3.3mA typical |
|---|---|
