TDA7116FHTMA1

IF发送器, 866MHz至870MHz, ASK, FSK, 20Kbps, 10dBm, 2.1V至4V, TSSOP-10

Description:

The TDA7116F is a single chip ASK/FSK transmitter for operation in the frequency band 866 ... 870 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.
