RFX1010 Block Diagram Low noise amplifier Transmit/receive switch circuitry Description High transmit signal linearity meeting standards for OQPSK The RFX1010 is a broadband, fully integrated, single-chip, modulation single-die RFeIC (RF front-end integrated circuit) that incorporates Low voltage (1.2V) CMOS control logic all the RF functionality needed for a TDD-mode RF front-end ESD protection circuitry on all pins DC grounded RF Ports operated in the 700 / 800 / 900 MHz frequency bands. Internal RF decoupling on all VDD bias pins The RFX1010 architecture integrates a linear PA, LNA, transmit Low noise figure for the receive channel and receive switching circuitry, associated matching networks, and harmonic filters all in a CMOS single-chip device. The High-power handling capability for received signals RFX1010 requires minimal external components including the Very low DC power consumption power supply bypass capacitors. Full on-chip matching and decoupling circuitry This RFeIC is designed for medium to high output power, and Minimal external components required consumes low current in receive mode. The combination of 50 input/output matching superior output power, high sensitivity and efficiency, low noise, Market-proven low-cost CMOS technology small form factor, and low cost makes the RFX1010 an ideal solution for multiple applications including IEEE 802.15.4, Small QFN (16-lead,3.0 x 3.0 x 0.55 mm) package with exposed ZigBee , AMR, smart home area network and other ISM ground pad applications in the sub-GHz bands from 780 to 960 MHz. It can also be used for IEEE 802.11p and 802.11ah. Skyworks Green products are compliant with A functional block diagram is shown in Figure 1.
