Visitors to the ANADIGICS booth (No. 3514) at the 2012 IMS can learn more about the model ALT6181. This multimode, multiband power amplifier (MMPA) module features separate single-ended amplifier chains for GSM/EDGE and WCDMA/LTE/CDMA2000 applications. For GSM and EDGE, the module operates as a fixed-gain amplifier; for LTE and CDMA, several different power modes are available to optimize efficiency. For example, the ALT6181 amplifier module offers a low-power mode for use at 0.5 V. It is based on indium-gallium-phosphide (InGaP) heterojunction-bipolar-transistor (HBT) monolithic-microwave-integrated-circuit (MMIC) technology and housed in a surface-mount package measuring just 5.0 x 7.5 x 0.9 mm.

In addition to its lines of LTE amplifiers, the firm will offer a variety of its many component solutions for wireless applications, including amplifiers and amplifier duplexers. Also, ANADIGICS' Director of Product Marketing for Broadband RF Products, Glenn Eswein, will be making a presentation on small-cell wireless infrastructure power amplifiers. The presentation takes place on Wednesday, June 20, 3 p.m., at Richardson RFPD Booth No. 1818.
