MO-TX4915-F
FSK TRANSMITTER MODULE
315/434/868/914MHz FSK TRANSMITTER
Description
MO-TX4915-F are FSK transmitter modules. The MO-TX4915-F is
an entire Phase-Locked Loop (PLL) for precise local oscillator generation. It
can use in OOK / HCS / PWM signal and modulate to transmit signal to
receiver device by air .It had a high performance and easily to design your
product. It can be used on wireless security system or specific
remote-control function and others wireless system.
Now we supports 315MHz/433.92MHz/868.35MHz/914.5MHz for ISM
Band modules can be selected
