AX5031_16 Datasheet, PDF (1/22 Pages) ON Semiconductor – Advanced Multi-channel Single Chip UHF Transmitter

AX5031
Advanced Multi-channel
Single Chip UHF Transmitter
OVERVIEW
The AX5031 is a true single chip low−power CMOS transmitter
primarily for use in SRD bands. The on−chip transmitter consists of a
fully integrated RF front−end 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
temperature range of −40°C to 85°C, it consumes 11 − 45 mA for
transmitting, depending on the output power.
