CWT2043 Description
CWT2043 can deliver up to 15W as a highly integrated single-chip wireless medium power transmitter IC. It can be configured to receive its input power from USB or AC adapter. Our chip integrates a power amp driver, a precise clock generator for PA frequency control, and munication controllers which use Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK).
