SA608DK/01,118

RF Mixers Overview

The SA608DK/01,118 is a low-voltage, high-performance monolithic FM IF system by NXP USA Inc., housed in a 20-SSOP package. It integrates a mixer/oscillator and two limiting intermediate frequency amplifiers with quadrature detection. Designed for portable communication applications, it operates down to 2.7V with typical current consumption of 3.5mA at 3V. The RF section mirrors the NE605 architecture, supporting frequencies up to 150MHz. Key parameters include a conversion gain of 17dB at 45MHz and a noise figure of 6.2dB. It features an internal audio output stage suitable for direct speaker drive.

RF Mixers Feature Summary

RF Mixers Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm RoHS3 compliance and REACH status prior to integration. Check datasheet revisions for any parameter updates. Ensure ESD handling protocols are followed during assembly. Validate supply chain documentation against official NXP part identification records.

RF Mixers Selection Notes

Choose this component when designing low-voltage FM receiver systems requiring integrated IF processing. Consider its 2.7V minimum operating voltage for battery-powered applications. Evaluate the 20-SSOP package constraints for PCB layout. Compare performance metrics like noise figure and gain against alternative mixers if specific sensitivity requirements exist.

RF Mixers Part Context

Part of the SA6xx series RF/IF building blocks from NXP Semiconductors. This series provides complete solutions for FM broadcast reception and related communication applications. The SA608 specifically targets cost-sensitive portable devices where space and power efficiency are critical design factors.

RF Mixers Replacement Considerations

SA606D/01,118 offers similar functionality but lacks the integrated audio amplifier and quadrature detector found in the SA608.
