Smallest triple-band E-GSM/DCS/PCS transmitter module

23 October 2002 Telecoms, Datacoms, Wireless, IoT

Mitsubishi Electric and the Electronic Component Group of Kyocera have introduced what they claim is the world's smallest triple-band compatible E-GSM/DCS/PCS transmitter module for cellular phone applications. The device occupies only 0,1 cm3. The transmitter module attains its remarkably small size primarily through design improvements that enable an 83% size reduction of the RF section area, compared to traditional discrete circuitry. The transmitter module integrates an antenna switch module, RF power amplifier, and RF output power monitor coupler in the same unit, along with an EN61000-compliant electrostatic discharge protection circuit. It features Mitsubishi Electric's new high efficiency InGaP/HBT/MMIC design and manufacturing technologies and Kyocera's high Q-factor LTCC substrate and low-loss antenna switch technologies.
