SA636BS,115

RF Mixers Overview

The SA636BS,115 is a low-voltage high-performance monolithic FM IF system IC manufactured by NXP USA Inc. It integrates a mixer/oscillator, two limiting intermediate frequency amplifiers, and a high-speed RSSI into a compact package. Designed for RF applications up to 500MHz, it supports cellular, ASK, DECT, FSK, UHF, and VHF systems. The device operates on a single supply voltage ranging from 2.7V to 5.5V with a typical supply current of 6.5mA. It features an 11dB gain and a 12dB noise figure, housed in a 20-HVQFN (4x4) surface-mount package.

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm the specific suffix '115' matches the required 20-HVQFN packaging variant. Check RoHS compliance status against current environmental regulations. Validate that the integrated RSSI functionality aligns with system requirements before procurement.

RF Mixers Selection Notes

Select this component for designs requiring integrated RF mixing and signal strength monitoring in a small footprint. Ensure the operating voltage range of 2.7V to 5.5V fits the power budget. Consider the 500MHz frequency limit for signal bandwidth. Verify compatibility with the 20-HVQFN thermal pad soldering process during PCB layout.

RF Mixers Part Context

This part belongs to the SA636 series of low-voltage high-performance monolithic FM IF systems. It shares core functional blocks with variants like SA636DK but differs in packaging and specific integration features such as the up-converter capability. The series is designed for compact wireless applications requiring integrated analog signal processing.
