Philips Semiconductors

High performance low power FM IF system

Product specification

NE/SA604A

DESCRIPTION

The NE/SA604A is an improved monolithic low-power FM IF system

incorporating two limiting intermediate frequency amplifiers,

quadrature detector, muting, logarithmic received signal strength

indicator, and voltage regulator. The NE/SA604A features higher IF

bandwidth (25MHz) and temperature compensated RSSI and

limiters permitting higher performance application compared with the

NE/SA604. The NE/SA604A is available in a 16-lead dual-in-line

plastic and 16-lead SO (surface-mounted miniature) package.

FEATURES

• Low power consumption: 3.3mA typical

• Temperature compensated logarithmic Received Signal Strength

Indicator (RSSI) with a dynamic range in excess of 90dB

• Two audio outputs - muted and unmuted

• Low external component count; suitable for crystal/ceramic filters

• Excellent sensitivity: 1.5µV across input pins (0.22µV into 50Ω

matching network) for 12dB SINAD (Signal to Noise and Distortion

ratio) at 455kHz

• SA604A meets cellular radio specifications
