Wireless Control Transmitter

The Wireless Control Transmitter series from Infineon is made up by a group of very low power consumption single ASK/FSK Transmitter for the sub 1 GHZ frequency bands. The ICs offer a high level of integration and need only a few external components.

The devices contain a fully integrated PLL synthesizer and a high efficiency power amplifier to drive a loop antenna. A special circuit design and a unique power amplifier design are used to save current consumption and therefore to save battery life. Additionally, features like a power down mode, a low power detect, a selectable crystal oscillator frequency and a divided clock output are implemented. The devices are offered in TSSOP-16 and TSSOP-10 package variants.

If your application allows for reduced requirements (e.g. limited temperature range), Infineon offers with its TDA71xx(F) family high quality transmitter products at low cost dedicated for non automotive applications.

The new SmartLEWIS™ TX is the next generation low power ASK/FSK transmitter supporting multi-band, multi-channel and lowest current consumption. The device includes a Sigma-Delta fractional-N PLL synthesizer to cover the main ISM frequency bands with only one crystal oscillator. More
