SA636DK/02J

RF Mixers Overview

The SA636DK/02J is a low-voltage, high-performance RF mixer manufactured by NXP Semiconductors. Designed for FM IF systems, it integrates a high-speed RSSI function within a single IC. The device operates on a supply voltage range of 2.7V to 5.5V and consumes 6.5mA of current. It supports frequencies up to 500MHz with a noise figure of 12dB and provides 11dB gain. Packaged in a 20-SSOP surface-mount format, this silicon-based component is suitable for mobile, ASK, DECT, FSK, UHF, and VHF applications.

RF Mixers Procurement Notes

Verify the specific ordering suffix /02J against the manufacturer's latest documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status as required by project standards. Check component lifecycle status, as availability may be limited due to end-of-life designations. Ensure compatibility with existing PCB footprint and assembly processes before finalizing procurement decisions.

RF Mixers Selection Notes

Select this component when a compact solution combining mixing and RSSI is required for low-power wireless designs. The 20-SSOP package suits space-constrained layouts. Evaluate the 12dB noise figure and 11dB gain against system sensitivity requirements. Consider the 2.7V minimum supply voltage for battery-operated applications requiring efficient power management.

RF Mixers Part Context

Part of the SA636 series, which includes variants like SA636BS and SA636DK/01. These components serve as building blocks for RF/IF circuits. The SA636DK/02J specifically targets FM IF applications with integrated signal detection capabilities. It complements other NXP wireless ICs by providing essential downconversion and monitoring functions in a single small outline package.

RF Mixers Replacement Considerations

SA636DK/01,112 offers similar electrical characteristics but differs in packaging. Verify pinout compatibility and thermal performance if substituting. Review datasheet revisions for any functional changes between variants.
