Transmitter 434 MHz ASK/FSK Transmitter

The TDA7100 is a single chip ASK/FSK transmitter for operation in the frequency band 433-435 MHz. The IC offers a high level of integration and needs only a few external components. The device contains a fully integrated PLL synthesizer and a high efficiency power Amplifier to drive a loop Antenna A special circuit design and an unique power Amplifier design are used to save current consumption and therefore to save battery life. Additional features are a power down mode and a divided Clock output. By Infineon Technologies Corporation
