SA604AD/02J

Overview

The SA604AD/02J is a high-performance, low-power FM intermediate frequency (IF) system integrated circuit manufactured by NXP Semiconductors. Designed for mobile applications, this single-channel RF amplifier operates at a center frequency of 25 MHz with a gain of 39 dB. It functions within a supply voltage range of 4.5 V to 8 V while drawing only 3.3 mA of operating current. The component utilizes silicon technology and is housed in a 16-SOIC surface-mount package. It supports an industrial temperature range from -40°C to +85°C and includes RSSI functionality.

Feature Summary

• Integrated FM IF system designed for high performance and low power consumption
• Includes Received Signal Strength Indicator (RSSI) capability
• Single-channel architecture optimized for mobile amplification tasks

Applications

• FM intermediate frequency processing in mobile devices
• ASK and FSK demodulation systems
• Mobile cellular amplifier circuits

Procurement Notes

Verify the obsolete status of the SA604AD/02J before initiating any procurement activities. Official documentation indicates the part is no longer manufactured. Confirm availability through authorized distributors or secondary market sources, as standard factory supply chains may not support new orders. Ensure compatibility with existing designs given the end-of-life designation.

Selection Notes

Select this component only if the design specifically requires a 25 MHz FM IF solution with integrated RSSI. Consider the 16-SOIC package constraints and industrial temperature rating during layout. Evaluate alternative active components if long-term supply stability is required, as this specific part number is discontinued. Verify that the 4.5 V to 8 V supply range aligns with the target system power architecture.

Part Context

The SA604AD/02J belongs to the SA604A series of RF ICs and modules produced by NXP Semiconductors. It is categorized under wireless and RF integrated circuits, specifically targeting FM IF system applications. The device represents a specialized solution for mobile communication hardware requiring efficient signal processing at intermediate frequencies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must identify functional equivalents based on specific electrical requirements such as 25 MHz operation and SOIC-16 packaging.
