¡El RFX1010 is a broadband, fully integrated, single-chip, single-die RFeIC (RF front-end integrated circuit) that incorporates all the RF functionality needed for a TDD-mode RF front-end operated in the 700 / 800 / 900 MHz frequency bands. ¡El 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. ¡El combination of superior output power, high sensitivity and efficiency, low noise, small form factor, and low cost makes the RFX1010 an 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 960 MHz. It can also be used for IEEE 802.11p and 802.11ah. A functional block diagram is shown in Figure 1. ¡El pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1.
