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
