WF4455TD

WF4455TD is a low-power and high-performance 433MHz short-range wireless communication transmitter circuit, which supports ASK modulation mode. All of its tuning can be automatically completed in the chip. PLL and power amplifier are integrated in the chip. WF4455TD has the characteristics of low power consumption, wide working voltage and high output power. In wf4455TD, PLL and power amplifier are integrated, in which PLL provides carrier signal for transmitter, PLL in wf4455TD has low working frequency points (433M and 315m), adopts local oscillator signal provided by ring oscillator, fixed frequency division circuit in the loop, and built-in loop filter. The overall power consumption is controlled below 1mA. The power amplifier amplifies the input signal with open drain output and external choke inductor. π - type narrow-band matching network is used to improve harmonic suppression and ensure the output signal power is greater than 13dbm. Wf4455TD is packaged with SOT23-6.

WF306TBM

Wf306TBM is an ook / ask radio frequency transmitter chip integrated with MCU function, with transmission power up to 12dbm and frequency range of 240mhz-450mhz. Wf306tbm can change frequency and power freely through software. It is used in various wireless remote control fields, such as anti-theft device, wireless doorbell, intelligent socket, remote control rolling shutter door and window, security alarm, light control, etc.
