AX5031 Advanced Multi-channel Single Chip UHF Transmitter OVERVIEW The AX5031 is a true single chip lowpower CMOS transmitter primarily for use in SRD bands. The on chip transmitter consists of a www.onsemi.com fully integrated RF frontend with modulator, and demodulator. Base band data processing is implemented in an advanced and flexible communication controller that enables user friendly communication via the SPI interface. AX5031 can be operated from a 2.2 V to 3.6 V power supply over a 1 temperature range of 40C to 85C, it consumes 11 45 mA for QFN20 4x4, 0.5P transmitting, depending on the output power.
