 New Product Family Marks Industry’s First Monolithic RF Solution To Optimize
                     Doherty Power Amplifier Performance

TAMPA, Fla. -- June 3, 2014

In Booth #515, Peregrine Semiconductor Corp. (NASDAQ: PSMI), founder of RF SOI
(silicon on insulator) and pioneer of advanced RF solutions, debuts its new
line of UltraCMOS^® Monolithic Phase & Amplitude Controllers (MPAC), the
industry’s first monolithic RF solution to maximize Doherty amplifier
performance. Through a digital interface, MPAC enables alignment of the phase
and amplitude between the Doherty amplifier’s carrier and peaking paths.
Designed for wireless infrastructure applications, MPAC improves system
performance, lowers costs, increases reliability and provides maximum tuning

“Doherty architectures have long been plagued by difficulties in optimizing
performance, which leads to higher manufacturing and engineering costs,” says
Duncan Pilgrim, Peregrine’s vice president of marketing. “MPAC provides an
ideal solution for this RF challenge and does so monolithically through
intelligent integration—something gallium arsenide (GaAs) technologies could
never achieve. Once again, Peregrine is introducing a superior UltraCMOS
product that will disrupt GaAs-based alternatives.”

MPAC Is the Wireless Infrastructure Solution

While widely used in the wireless infrastructure industry, Doherty amplifiers
require a considerable engineering investment to manually implement and
optimize. Any mismatch or misalignment in phase and amplitude between the
Doherty architecture’s carrier and peaking paths can quickly contribute to
higher costs and degradation of the system’s overall performance. Even after
optimizing with discrete components, the system remains inflexible to
manufacturing variances from power amplifier assemblies.

MPAC solves this engineering challenge with the industry’s first monolithic
solution to maximize asymmetric and symmetric Doherty amplifier performance.
With more than 25 years of RF expertise, Peregrine leverages superior
technology, a sophisticated IP portfolio and advanced product knowledge to
develop solutions for complex RF challenges such as Doherty amplifier
optimization. MPAC also integrates Peregrine’s industry-leading digital step
attenuators and phase shifter products onto a single die.

On an UltraCMOS chip, each MPAC product includes:

  *90-degree hybrid splitter
  *Two phase shifters
  *Two amplitude controllers
  *Digital SPI interface

MPAC offers RF engineers improved system performance, lower costs, increased
reliability and maximum tuning flexibility for either LDMOS (laterally
diffused metal oxide semiconductor) or GaN (gallium nitride) based Doherty
power amplifier architectures. MPAC performance advantages include
improvements in power added efficiency, linearity across the frequency range,
Doherty bandwidth through better matching and effectiveness of the digital
pre-distortion (DPD) loop. MPAC reduces bill of materials (BOM) costs by
eliminating the need for external components such as DC blocking capacitors
and reducing component count for greater board area. It also lowers costs by
providing tighter production distributions on expensive power amplifier
assemblies. With uniformity and repeatability between transceiver paths, MPAC
increases system reliability and increases transceiver yield. Finally, MPAC
delivers improved flexibility with adjustable phase and amplitude tuning for
each independent path through the SPI digital interface. This flexibility
enables real-time adjustments in order to optimize for operational or
environmental changes.

The Time Is Now

The explosive growth of the LTE market has fueled demand for Doherty
architectures, and this demand will increase with LTE-A requirements. Both LTE
and LTE-A need high peak-to-average ratios (PAR), and the Doherty architecture
provides an ideal solution for optimizing amplifier performance. Due to its
lower cost, the market has largely adopted asymmetric Doherty amplifiers,
which receive the maximum MPAC benefits due to their complex performance

“Despite a relatively flat market value in base stations, transceiver
shipments will grow by 8 percent annually over the next five years,” says Joe
Madden, founder and principal analyst at Mobile Experts. “At the same time,
several features of LTE and LTE-A are creating a need for tighter control over
Doherty amplifier performance. The market needs low-cost solutions that
improve phase and amplitude precision.”

Features & Availability

With a wide positive and negative phase shift range and a fine step size, MPAC
delivers high linearity of 65 dBm IIP3 and extremely low power consumption of
300 µA. It provides performance advantages in power handling and port-to-port
isolation. As MPAC is built on an UltraCMOS monolithic chip, RF engineers can
rest assured with the most reliable and repeatable solution on the market.
UltraCMOS technology enables superior ESD performance of 1 kV, an extended
temperature range up to 105-degree Celsius and a wide power supply range from
2.7 to 5.5 V.

The first product in the MPAC family is the PE46120. Currently being sampled
to select customers, the PE46120 covers a frequency range of 1.8 to 2.2 GHz.
The MPAC product family plans to cover all cellular frequency bands.

talk with a technical expert. Additional information can also be obtained
