Alps has completed development of its TSM 1-6 series of FM transmitter modules for use with mobile phones and other small portable devices.

With its eyes firmly fixed on the need for miniaturisation and high functionality, Alps has developed the industry's smallest FM transmitter module.

Electronic components that are equipped with an FM transmitter can use FM broadcast waves to transmit audio data.

For example, an MP3 player equipped with this new module can transmit recorded music via FM waves to an FM car stereo, thus enabling passengers to playback and enjoy the music.

Development of this module, which fits on a human fingertip, was made possible by Alps' long-held lead in high-frequency wave design technology and high-density mounting technology.

Knowhow in each of these areas was essential for meeting the increasing demand for miniaturisation and multifunctionality.

In addition, thermal resistance simulations were conducted during reflow mounting tests to ensure a high level of reliability that is fully compatible with miniaturisation efforts.

By guaranteeing module performance, it is possible to minimise performance testing and delivery inspections of the manufactured product.

This simplifies product engineering and helps shorten the production process.

This exceptional module also incorporates an integral radio data system (RDS) function.

Audio data that is sent to a compatible tuner can be superimposed with the name of the song, the artist's name, or other textual information.

Furthermore, in order to comply with the international regulations that govern radio transmission and ensure electromagnetic compatibility (EMC), the antenna reduces unnecessary emissions that might otherwise disrupt wireless communication.

The product is available with antennas for four output control levels that vary according to the configurations and properties of the components.

This greatly enhances the product design process.
