SA636DK/01,112

RF Mixers Overview

The SA636DK/01,112 is a low-voltage high-performance RF mixer manufactured by NXP USA Inc. Designed for FM IF systems with high-speed RSSI, it operates within a supply voltage range of 2.7 V to 5.5 V and consumes 6.5 mA. The device features a single mixer with 11 dB gain and 12 dB noise figure, supporting frequencies up to 500 MHz. It is housed in a 20-SSOP surface-mount package.

RF Mixers Feature Summary

• Integrated high-speed Received Signal Strength Indicator (RSSI) functionality
• Optimized for low-voltage operation down to 2.7 V
• High bandwidth design suitable for portable communication applications

RF Mixers Applications

• FM IF systems
• Portable cellular communications
• ASK modulation systems
• DECT applications

RF Mixers Procurement Notes

Verify component status as the SA636DK/01,112 is classified as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any replacement components maintain compatibility with the original 20-SSOP footprint and electrical specifications required for the specific application design.

RF Mixers Selection Notes

Select this component for designs requiring integrated mixing and signal strength monitoring in low-power environments. The device supports various modulation types including ASK, FSK, and DECT. Consider the 20-SSOP package dimensions and thermal requirements during PCB layout. Verify that the 500 MHz frequency limit meets the system's operational bandwidth needs.

RF Mixers Part Context

Part of the SA636 series, designed for high-bandwidth portable communication. The RF section architecture is similar to the SA605. It serves as an RF building block for wireless applications, combining mixing functions with RSSI output in a compact surface-mount package suitable for consumer electronics and mobile devices.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers must evaluate alternative mixers with compatible pinouts, voltage ranges, and performance metrics for direct replacement.
