Optichron® Combines Latest DPD IC and GaN Transistors to Deliver Breakthrough RF Power Amp Performance With 56% PAE and 50 MHz Bandwidth

Application Note Describes 2.14 GHz Single Transmit Path Demonstrating 2G, 3G and 4G Protocols

FREMONT, CA--(Marketwire - May 24, 2010) -  Optichron, Inc., the leader in digital nonlinear signal processing, today announced the results of testing the combination of Optichron's OP6180 Digital Pre-Distortion (DPD) IC with a Doherty Power Amplifier (PA) based on Sumitomo Electric Device Innovations, Inc.'s (SEDI) latest-generation GaN transistors. The result is breakthrough efficiency at over 47 dBm transmitted power. SEDI's EGN21C105I2D is a 2.14 GHz 105W device featuring wideband performance and exceptional efficiency. Combining high transmit performance with high power added efficiency (PAE), the PA delivers up to 50 MHz of signal bandwidth with PAE up to 56.7% and supports all 2G, 3G and 4G protocols. There will be a live demonstration of the DPD and PA in SEDI booth #1333 at the MTT Microwave Symposium in Anaheim from Tuesday, May 25 through Thursday, May 27, 2010.

Optichron has published an application note, titled Advances in Digital Pre-Distortion with GaN Devices, including performance details and how to use the available tools from Optichron to implement the PA. The application note describes a single 2.14 GHz transmit path combining Optichron's industry-leading OP6180 DPD and SEDI's latest GaN transistors. The combined solution is capable of supporting GSM Class 1 or Class 2, WCDMA and LTE protocols with up to 50 MHz of signal bandwidth and up to 56.7% PAE.
