SA616DK/02,118

RF Mixers Overview

The SA616DK/02,118 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, two limiting IF amplifiers, a quadrature detector, logarithmic RSSI, voltage regulator, and audio/RSSI op amps. Designed for portable communications, it operates down to 2.7 V with typical supply current of 3.5 mA at 3 V. The RF section supports inputs up to 150 MHz, offering 17 dB conversion gain at 45 MHz. It features 102 dB IF amp/limiter gain, 2 MHz bandwidth, and an 80 dB dynamic range RSSI.

RF Mixers Feature Summary

• Integrates complete FM IF system including mixer, oscillator, limiters, and quadrature detector
• Provides temperature-compensated logarithmic RSSI with wide dynamic range
• Enables flexible output adjustment via accessible feedback paths for audio and RSSI op amps

RF Mixers Applications

• Portable communication systems
• FM intermediate frequency processing
• Cellular transceivers requiring RSSI monitoring

RF Mixers Procurement Notes

Verify component obsolescence status prior to procurement as the manufacturer has indicated scheduled discontinuation. Confirm that the specific suffix DK/02,118 matches the required pinout and functional configuration, as variations within the SA616 series may exist. Ensure design-in timing accounts for potential supply constraints associated with end-of-life components.

RF Mixers Selection Notes

Select this component when a fully integrated FM IF solution is required with minimal external passive components. It is suitable for designs prioritizing low power consumption and compact footprint. Consider the 150 MHz upper frequency limit and 2.7 V minimum operating voltage against system requirements. Evaluate the availability of replacement parts due to the discontinued status.

RF Mixers Part Context

This part belongs to the SA6xx Series of RF/IF building blocks from NXP Semiconductors. These devices are designed to simplify radio receiver architectures by combining multiple functions into a single monolithic IC. The SA616 specifically targets FM applications, offering a cost-effective alternative to discrete solutions while maintaining high performance in portable devices.
