TiaLinx, Inc. Launches High-Efficiency Class-E and Class-F Switching Power Amplifiers as Part of the Cheetah Cluster of Core Designs

NEWPORT BEACH, Calif., April 17, 2008 — TiaLinx, Inc., a developer of wafer scale integrated radio and antenna array, today announced launch of its highly efficient switching mode power amplifier core designs to address Electronically Scanned Arrays (ESA).

"The core designs were developed with the support of Office of Naval Research's contract number N00014-07-M-0268 and DARPA's W31P4Q-06-C0380 for development of ESA," commented Dr. Fred Mohamadi, Founder and CEO of TiaLinx. "Digitally programmable waveform distribution and beamforming architecture exploits advanced and highly efficient 'digital' switched-mode amplifiers and is of immense interest to implementing wafer scale antenna arrays. Reduced components, size, weight, power consumption and increased efficiency are achieved compared to the conventional approaches based on heterodyning (analog up-conversion) and analog beamforming."

Recent advances in both wide-bandgap semiconductors based switched-mode amplifiers have demonstrated power added efficiencies (PAE) of 57% for GaN MMICs Class-E amplifiers. Using Si-Ge technology, TiaLinx is introducing Class-E and Class-F switching power amplifiers with PAE of about 45-65% at K-and V-bands. ESA can exploit these high efficiencies and are expected to eventually replace more conventional arrays.
