SA616DK/03,118

RF Mixers Overview

The SA616DK/03,118 is a low-voltage high-performance monolithic FM IF system by NXP USA Inc. It integrates a mixer/oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, logarithmic RSSI, voltage regulator, and audio/RSSI op amps. Designed for portable communication applications, it operates down to 2.7 V with typical current consumption of 3.5 mA at 3 V. The device supports frequencies up to 150 MHz, offering 17 dB conversion power gain at 45 MHz and 102 dB IF amplifier gain. It features an 80 dB dynamic range RSSI and is housed in a 20-pin SSOP package.

RF Mixers Procurement Notes

Verify the specific ordering suffix '03' against official NXP documentation to confirm pinout or variant differences compared to standard '01' versions. Confirm component status as obsolete prior to procurement planning. Ensure compatibility with existing PCB footprints and design-in requirements given the discontinued status of this specific part number.

RF Mixers Selection Notes

Select this component for designs requiring a highly integrated FM IF solution with minimal external components. Consider the 2.7 V minimum operating voltage for low-power constraints. Evaluate the 150 MHz frequency limit against target RF specifications. Note the obsolete status may necessitate long-term supply risk assessment or alternative sourcing strategies.

RF Mixers Part Context

Part of the SA6xx series RF/IF building blocks from NXP. This series provides compact solutions for wireless communication applications. The SA616 specifically targets FM IF processing, combining multiple functions into a single chip to reduce board space and complexity in portable electronic devices.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Due to the obsolete status, direct replacement requires evaluating functional equivalents from other manufacturers or redesigning around newer NXP portfolio members.
