NE/SA604A
High performance low power FM IF system
397
1994 Dec 15
853-1431 14477
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
