433M Wireless Transmitter Receiver Module
A low-power 433MHz transmitter is designed using 0.18um CMOS process for battery-less TPMS.
It is mainly composed of a PLL frequency synthesizer and a PA, and the transmitter is achieved in a fully integrated chip except for the choke and output match inductor of PA.
Based on post-simulation, locked time and phase noise of the PLL are respectively about 60us and −105dBm/Hz@300kHz, the power consumption of the transmitter is 25mW when the output power of PA is 7dBm.
The area of the whole transmitter is 1mm × 1mm, including ESD pads.
