Enhanced Performance

Powerful hardware features like antenna diversity and external power amplifier support let you further boost transceiver performance to maximize network reliability and the RF range of your system. Microchip transceivers support not only IEEE 802.15.4-compliant applications, but provide on-air data rates up to 2Mbit/s for general purpose ISM applications.

To help you speed system development and prototyping, Microchip offers a variety of free software suites, various hardware evaluation and development kits, and RF Modules.

Key Products

The AT86RF212B is a low-power, low-voltage RF transceiver for the regional 700/800/900 MHz frequency bands available in Japan, China, Europe and North America. This transceiver offers an extreme 120 dB link budget (-110 dBm receiver sensitivity / 10 dBm transmit power) designed for low-cost IEEE 802.15.4, ZigBee, 6LoWPAN, and high-data-rate ISM (industrial, scientific, medical) applications.

The Microchip AT86RF233 transceiver is designed to operate in the 2.4GHz ISM band, available worldwide. The device supports the physical layer used for ZigBee Pro and ZigBee IP. With 4 dBm transmit power and receiver sensitivities down to -101 dBm, 105 dB link budget can be achieved.

The AT86RF215 is a dual-band sub-1GHz/2.4 GHz transceiver compliant to IEEE 802.15.4g-2012 and ETSI TS 102 887-1. An output power of 14 dBm and receiver sensitivities down to -123 dBm result in an outstanding link budget of up to 137 dB. The device offers a high flexibility by supporting a variety of data rates with three modulation schemes: multi-rate and multi-regional frequency shift keying (MR-FSK), orthogonal frequency division multiplexing (MR-OFDM), as well as offset quadrature phase-shift keying (MR-O-QPSK). Simultaneous operation at sub-1GHz and 2.4 GHz enables new capabilities and the right cost structure in smart metering, smart lighting, home energy gateways, and other industrial and automation equipment.
