Product specification
High performance low power FM IF system
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.

AC ELECTRICAL CHARACTERISTICS
Typical reading at TA = 25°C; VCC = ±6V, unless otherwise stated. IF frequency = 455kHz; IF level = -47dBm; FM modulation = 1kHz with ±8kHz peak deviation. Audio output with C-message weighted filter and de-emphasis capacitor. Test circuit Figure 3. The parameters listed below are tested using automatic test equipment to assure consistent electrical characterristics. The limits do not represent the ultimate performance limits of the device. Use of an optimized RF layout will improve many of the listed parameters.

NOTE: 1. NE604 data sheets refer to power at 50 input termination; about 21dB less power actually enters the internal 1.5k input. NE604 (50) NE604A (1.5k)/NE605 (1.5k -97dBm -118dBm -47dBm -68dBm +3dBm -18dBm The NE605 and NE604A are both derived from the same basic die. The NE605 performance plots are directly applicable to the NE604A.
