Altair Semiconductor Ltd has developed the FourGee-6150 Long Term Evolution RF transceiver, which supports the baseband processors for mobile WiMAX and XGP, offering a broad 4G capability.

The device operates in the 1.9GHz to 2.7GHz band and integrates voltage-controlled oscillator, PLL, power amplifier driver and LNA, and is optimized for use with Altair's FourGee baseband processor series for LTE, WiMAX and XGP. The design is a single-conversion architecture implemented in CMOS and comes in a 4.4mm x 2.9mm WLCSP package.

"Having an RF transceiver developed in-house is one of the cornerstones of Altair's strategy for LTE," said Oded Melamed, co-founder and CEO of Altair. "The LTE landscape is much more complex than that of other 4G technologies due to the fragmented global spectrum map and varying combinations of frequency bands and duplex methods. The investment required to develop a global LTE solution is significant. This, combined with the fact that most of a chipset's value lies within the baseband processor, has left many pure play RF transceiver companies reluctant to invest in the technology."

"Offering a complete chipset solution that covers worldwide frequency bands and duplex methods puts Altair in a strong position as LTE technology rolls out in the coming months," said Eran Eshed, co-founder and vice president of marketing and business development for Altair.

Altair is also working on the FourGee-3100 LTE baseband processor, the FourGee-6200 multiband LTE-FDD MIMO transceiver for frequency bands in North America, Japan and Europe, and the data card for the purposes of testing, IOT and field trials, available to order in Q4 09.
