AT86RF211SAH-R

RF Transceiver ICS Overview

The AT86RF211SAH-R is a monolithic RF transceiver IC designed for sub-1 GHz ISM bands, operating within the 400 MHz to 950 MHz frequency range. It integrates a transmitter, receiver, and synthesizer with an internal PLL and VCO, eliminating the need for external coils. The device supports FSK modulation and delivers up to 100 kbps data rates. Key electrical parameters include a maximum output power of 16 dBm and a sensitivity of -107 dBm. It functions on a 2.4 V to 3.6 V supply, drawing 24 mA during reception and 35 mA to 43 mA during transmission. The component utilizes SPI for serial communication and is housed in a 48-LQFP package.

RF Transceiver ICS Feature Summary

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'SAH' against official Microchip documentation to confirm it denotes the shrink version with reduced current consumption. Confirm that the part status aligns with project requirements, as availability may vary. Ensure the 48-LQFP package dimensions match the PCB footprint specifications. Cross-reference the datasheet revision date to ensure all feature activations and bit configurations are accurately understood for production migration.

RF Transceiver ICS Selection Notes

Select this component when a single-chip solution without external matching coils is required for sub-1 GHz operations. It is suitable for designs prioritizing high output power to enable the use of inexpensive printed antennas. Consider the 2.4 V to 3.6 V voltage range and SPI interface compatibility with the host microcontroller. Evaluate the thermal performance within the -40°C to 85°C operating range for the intended environment.

RF Transceiver ICS Part Context

This device belongs to the AT86RF211 family of multiband transceivers. The AT86RF211SAH-R represents a shrink version variant, characterized by a 20% reduction in current consumption while maintaining functional compatibility with the standard AT86RF211 after power-on reset. It serves as a direct replacement in existing production lines for users migrating from the original model, offering enhanced energy efficiency without altering the core architectural features.

RF Transceiver ICS Replacement Considerations

The AT86RF211SAH-R is documented as a direct replacement for the standard AT86RF211 in production environments. Migration kits are available for existing AT86RF211 users. Verify that the pinout remains identical between the standard and shrink versions to ensure seamless board-level substitution without redesigning the RF front-end or baseband connections.
