The RFX1010 is a broadband, fully integrated, single-chip, single-die
RFeIC (RF Front-end Integrated Circuit) which incorporates all the RF
functionality needed for a TDD-mode RF front-end operated in the
700/800/900MHz frequency bands.
The RFX1010 architecture integrates a linear PA, LNA, Transmit and
Receive switching circuitry, associated matching networks, and
harmonic filters all in a CMOS single-chip device. The RFX1010
requires minimal external components including the power supply
bypass capacitors.

This RFeIC is designed for medium to high output power, and
consumes low current in receive mode. The combination of superior
output power, high sensitivity and efficiency, low noise, small form
factor and low cost makes RFX1010 the ideal solution for multiple
applications including IEEE 802.15.4, ZigBee, AMR, Smart Home Area
Network and other ISM applications in the sub-GHz bands from 780 to
960MHz. It can also be used for IEEE 802.11p and 802.11ah.
