SA615DK/01,118

RF Mixers Overview

The SA615DK/01,118 is a high-performance monolithic low-power FM intermediate frequency system manufactured by NXP USA Inc. It integrates a mixer/oscillator, two limiting IF amplifiers, and a quadrature demodulator within a single package. Designed for surface-mount installation in a 20-LSSOP (4.40mm wide) housing, this component operates with a supply voltage ranging from 4.5V to 8V and draws a typical supply current of 7.4mA. The device supports RF frequencies up to 500MHz, offering a gain of 13dB and a noise figure of 5dB. It contains three mixers and is suitable for applications including cellular, ASK, FSK, UHF, and VHF up-conversion.

RF Mixers Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official NXP documentation before procurement. Confirm that the 20-LSSOP package dimensions match your PCB footprint requirements. Check current availability status as this component may be discontinued or subject to long lead times. Ensure compatibility with the required 4.5V to 8V supply voltage range for your target application design.

RF Mixers Selection Notes

Select this component when a complete FM IF solution is required within a limited board space. Consider its 500MHz frequency limit and 13dB gain characteristics for signal processing needs. Evaluate the 7.4mA supply current against power constraints. Verify that the 20-pin SSOP package is compatible with your assembly capabilities and thermal management strategy.
