Product Description

1.1

Overview

The TDK 5111 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.
