Scintera Announces Highly Integrated Dual-Path RF Predistortion Linearizers
Targeting Small Cells and Remote Radio Heads
SC2200 and SC2220 address small cell MIMO, DAS, AAS, RRH and multi-band
designs ranging from 250mW to 60W or more output power at the antenna
SUNNYVALE, Calif., May 29, 2013
SUNNYVALE, Calif., May 29, 2013 /PRNewswire/ --Scintera Networks, Inc., a
leading provider of mixed signal semiconductors for wireless communications,
today announced the availability of the SC2200 and SC2220 dual-path
system-on-chip (SoC) RF Power Amplifier Linearizers (RFPAL). Based on broadly
adopted and field-proven technology, the SC2200 and SC2220 extend the
capability and performance of Scintera's power amplifier (PA) linearization
solutions to further simplify and facilitate the design of multi-antenna
and/or multi-band cellular infrastructure systems.
The SC2200 supports systems with 20MHz of signal BW and power levels from
250mW (RMS) up to 5W (RMS) at the antenna. Applications include MIMO small
cells, distributed antenna systems (DAS), active antenna systems (AAS) and
multi-band SISO systems. The SC2220 supports systems with up to 75MHz signal
BW and power levels from 2.5W (RMS) up to 60W (RMS) or more at the antenna.
Applications include multi-antenna LTE remote radio heads (RRH), small cell
MIMO and high power multi-band base stations.
Scintera's cost-effective linearization solutions have given rise to a new
generation of low power Doherty amplifiers that are specifically designed to
operate with Scintera's RFPAL. The introduction of the SC2200 now makes
linearization of Class A/AB PAs economically feasible even for systems
operating at levels as low as 24dBm (RMS) at the antenna. Low power Doherty
PAs and even lower power Class A/AB PAs combined with Scintera's dual-path
linearizer delivers unprecedented transmitter efficiency to MIMO small cell
base stations, DAS and AAS.
"By integrating two independent linearization paths into one compact SoC, the
SC2200 and SC2220 continue to drive down the cost of multi-antenna and
multi-band cellular systems that demand high efficiency and excellent
linearity in lower output power cellular applications like operator-managed
indoor small cells," said Davin Lee, chief executive officer of Scintera.
"Small cells have struggled with achieving low power consumption in a very
small form factor. These new products specifically address applications where
multiple linearizers are required including LTE MIMO, systems with multiple
frequency bands and where arrays of transmitters need to achieve high
efficiency and linearity. The SC2200 and SC2220 will play a key role in the
deployment of small cells by enabling lighter and lower volume enclosures, the
use of Power over Ethernet (PoE) through low power consumption and fast time
to market by simplifying designs. All these benefits can be accomplished using
our latest family of dual-path linearizers at compelling price points."
The SC2200 and SC2220 provide additional features beyond linearization
including (per path) integrated pre-amplifier, temperature-compensated gate
biasing, triple RF power measurement (RFIN, PAOUT, and Reverse Power) and
temperature sensor. In addition, a configurable set of ADCs and DACs may be
used to measure the drain current and voltage of the final stage PA and set
the appropriate gate bias. The SC2200 and SC2220 are highly flexible and
adaptive RFin/RFout solutions supporting Class A/AB or Doherty RF PA designs
with an operating frequency from 698 MHz to 2700 MHz and cellular
communication protocols including CDMA/EVDO, TD-SCDMA, WiMAX, WCDMA/HSDPA, LTE
The SC2200 and SC2220 are packaged in an 80-pin, 11 mm x 11 mm QFN package
enabling the implementation of the entire predistortion linearization solution
in as little as 2.5 cm^2 of board space. The compact system solution is easily
integrated directly into the most restricted form factors including PA
International Microwave Symposium (IMS2013)
Scintera will be introducing their latest dual-path RFPALs (SC2200 and SC2220)
at the International Microwave Symposium, booth 2146, on June 4-6, 2013.
Scintera's products will also be showcased at other semiconductor vendor's
booths including Freescale Semiconductor (Booth 2003), Sumitomo Electric
Devices Innovations (Booth 2120), ANADIGICS (Booth 718) and Cree, Inc. (Booth
The SC2200 and SC2220 will be available in pre-production quantities in Q3
2013 and in mass production quantities in Q1 2014.
Scintera is an industry leader in delivering high performance, compact and
very low-power system-on-chip solutions to measure, modify and monitor RF
signals and systems. The company's programmable analog signal processing
architecture effectively combines digital programmability with the simplicity,
small size and low power consumption of analog circuit processing. The first
products to leverage this innovative architecture are its family of adaptive
RF predistortion linearizers. Scintera's RF power amplifier linearizers
(RFPAL) have achieved broad acceptance in the cellular infrastructure and
digital terrestrial broadcast markets. Wide deployment in the field has proven
that RFPAL can dramatically increase system efficiency and reduce costs in
existing applications and is now also enabling novel high performance, cost
sensitive and very compact 4G cellular systems. Scintera is privately held and
is headquartered in Sunnyvale, California. For further information, please
