SA615D/01,112

RF Mixers Overview

The SA615D/01,112 is a high-performance monolithic low-power FM IF system manufactured by NXP USA Inc. It integrates a mixer/oscillator, two limiting intermediate frequency amplifiers, and a quadrature detector within a single silicon chip. Designed for cellular, ASK, FSK, UHF, and VHF up-conversion applications, the device operates at frequencies up to 500MHz. Key electrical parameters include a supply voltage range of 4.5V to 8V, a typical supply current of 7.4mA, a gain of 13dB, and a noise figure of 5dB. The component is housed in a 20-SSOP package.

RF Mixers Procurement Notes

Verify the specific suffix (e.g., /01,112) against official NXP documentation to confirm package type and tape/reel specifications. Note that this part number may be discontinued; check current availability status with authorized distributors. Ensure compatibility with existing PCB footprints for the 20-SSOP or LSSOP variant before procurement.

RF Mixers Selection Notes

Select this component for designs requiring integrated RF mixing and FM detection in a compact form factor. Consider the 4.5V to 8V supply range when designing power management circuits. Evaluate the 500MHz maximum frequency limit against target signal bands. Assess thermal performance given the 7.4mA operating current in surface-mount packages.
