Collaborating with United Monolithic Semiconductors and
the Fraunhofer Institute for Applied Solid State Physics, NXP
Semiconductors is developing a gallium-nitride (GaN) process
technology that boosts performance of next-generation RF
power amplifiers.
The new GaN process, with its high frequency combined
with high power, puts NXP in the ideal position of being able
to support future applications while continuing to evolve its
well-established LDMOS technology.
The GaN technology delivers numerous benefits to
manufacturers of infrastructure equipment. Using the GaN
technology in a transmitter represents a significant cost savings
in system manufacturing, along with major improvements in
system performance and flexibility.

Most of today’s base station power amplifiers are limited to
specific applications. The new GaN-based technology lets
operators use a “universal transmitter” to switch between
systems and frequencies, so they can instantly meet demands
in the base station’s coverage area. GaN transistors enable
much more efficient power amplifiers and as a result drive
down the operational costs of telecom operators.
GaN transistors can operate at much higher junction
temperatures than Si- and GaAs-based devices, so GaN is
an ideal candidate for environments with reduced cooling
capabilities, such as tower-top base stations. Also, with its high
power densities, GaN has the potential to expand into other
areas, including high-power broadcast applications, where
solid-state power amplifiers built with vacuum tubes are still
the norm.
NXP’s first GaN broadband power amplifiers are expected
to be available in 2010, with Switch Mode Power Amplifiers
(SMPAs) following quickly thereafter.
