Product Description

CYF4455B 300MHz to 450MHz Transmitter ic

DESCRIPTION:
CYF4455B is a high-performance, easy-to-use single-chip ASK transmitter IC, suitable for long-range wireless applications in the 300-450MHz frequency band. This chip is a monolithic device that can truly achieve "data input, antenna output". CYF4455B has three powerful attributes: power output, working voltage and working temperature. CYF4455B can provide +14dBm for 50Ω load. This power level allows small transmitters (lossy antennas), such as key fob transmitters, to operate near the maximum limits of the transmission rules. 2.0V to 3.6V operating voltage, CYF4455B can be used with most batteries, reaching the limit of its use range. The operating temperature range is -20°C to +70°C.
