1.1
The TDK 5101 F is a single chip ASK/FSK transmitter for operation in the frequency band
311-317 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.
