NJM3359D

Overview

The NJM3359D is a low-power narrow band FM intermediate frequency (IF) integrated circuit manufactured by Nisshinbo Micro Devices Inc. Designed for cellular and PCS applications, this component operates with carrier frequencies of 10.7 MHz and 455 kHz. It integrates an RF oscillator, amplifier, and automatic frequency control (AFC) circuit within a single package. The device is housed in an 18-DIP (0.300 inch / 7.62 mm) through-hole package, suitable for standard printed circuit board assembly methods.

Feature Summary

• Integrates RF oscillator, amplifier, and AFC circuitry
• Optimized for low power consumption in narrow band FM IF applications
• Supports dual carrier frequency operation at 10.7 MHz and 455 kHz

Applications

• Cellular communication systems
• PCS (Personal Communications Service) devices
• Narrow band FM receiver front-ends
