TDK5110F Datasheet PDF - Infineon

●1.1 Overview

●The TDK 5110 F 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.
