Semiconductor Startup Xindium Unveils RF Power Amplifier With Integrated Power Control

Crystal Lake, IL -- Xindium Technologies, a developer of RF power amplifiers for mobile phones, has introduced a new power amplifier module for GSM and GPRS handset manufacturers.

The new power amplifier module, called the XPA 9133, is a quad-band, 7 mm by 10 mm GSM/GPRS InGaP HBT device with integrated power control, featuring excellent efficiency and ruggedness. The XPA 9133 features a pinout and a power control scheme that are similar to the current generation of 7 mm by 10 mm GSM/GPRS power amplifier modules, reducing the need for changes in circuit board design for GSM handset manufacturers.

Xindium is working with PA power control vendors to provide handset-ready PA/power control reference designs to GSM/GPRS handset OEMs and ODMs. These reference designs support either precision closed-loop power control or low-cost open-loop power control, with the burst and ramp profile quality necessary for high-yield volume handset manufacturing.

"The XPA 9133 gives manufacturers greater diversity in their PA supply base without compromising on cost, performance, size, or manufacturing yield," said John Brewer, Xindium CEO. "This power amplifier module demonstrates Xindium's ability to be a leader in the GSM power amplifier module market, and represents an excellent addition to Xindium's industry-leading InP DHBT technology base."

The XPA 9133 PA module provides nearly 60% efficiency at maximum output power for GSM900, and over 50% efficiency for DCS. The XPA 9133 supports tri-band and quad-band applications utilizing any combination of the GSM850, GSM900, DCS, and PCS bands. The XPA 9133 PA supports GPRS Class 12 operation.
