RFHIC RFP-2135-49-48GDMay 6, 2010 -- RFHIC Corporation recently released a 80W Gallium Nitride (GaN) power amplifier for LTE(Long Term Evolution) and WCDMA applications. Internal matched GaN on SiC (Silicon Carbide) transistor being the key building block, the amplifier shows 50dB gain at 48V. The GaN amplifier works throughout 2110-2140MHz(30MHz bandwidth) and shows 35% or higher efficiency rating by utilizing Doherty design & Digital Pre-distortion(DPD) technique. One single module includes DC/DC, detector, coupler and isolator functions within a small footprint of 170 x 175 x 28(mm). This GaN amplifier is already being deployed together with SK Telecom, the biggest Korean Mobile service provider, in selected sites.

Previous LDMOS (Laterally Diffused Metal Oxide Semiconductor) technology based Doherty amplifiers had several drawbacks such as limited efficiency and bigger size. Having higher efficiency throughout the 30MHz bandwidth and 6 channels were a challenge for LDMOS. LDMOS transistor package was larger and input/output matching patters were bigger, which all prohibited the power amplifier design to be smaller. These issues were also against the service providers request for a greener system design.

RFP-2135-49-48GD Response

RFHIC started using Gallium Nitride (GaN) technology since 2004. With extensive research and design experience, RFHIC accumulated technological breakthroughs in major areas such as internal matching, heat dissipation, Doherty designs, module optimization, MMIC design and package assembly. These experiences contributed on designing a better performance GaN power amplifier with lower cost for the telecommunication market.

RFHIC is now targeting 40% efficiency on the next revision.
Some other recently released products are 30W WCDMA/LTE amplifiers, 30W Cellular/CDMA amplifiers and 60W Cellular/CDMA amplifiers. Please contact rfsales@rfhic.com for more product details and specifications.
