NEUBIBERG, GERMANY and ATLANTA, GA , Infineon Technologies AG
(FRANKFURT: IFX) (NYSE: IFX) announced the availability of the
company's new low noise amplifier (LNA), one of the industry's
smallest broadband LNAs for portable and mobile TV applications.
The new BGA728L7 is the first mobile TV LNA worldwide to support
1.8V, 2.8V and 3.3V operations. It is optimized for a wide
frequency range covering VHFIII, UHF and L bands, and one of the
few mobile TV LNAs offering dual modes (high-gain mode and low gain
mode). At high-gain mode BGA728L7 helps to improve reception
sensitivity for weak signals through its best-in-class noise figure
of 1.4 dB combined with 16 dB gain. For a strong input signal the
BGA728L7 can be switched to a low-gain mode to offer higher
linearity with low current consumption of only 0.5 mA.
Mobile TV is a key feature for next-generation high-end
communication products, such as cellular phones, personal media
players and portable devices including laptops. According to a
report from the UK-based market research company Datamonitor,
mobile television is set to achieve massive growth over the next
years with a global market for such services to reach about 155
million subscribers by the end of 2012, up from just 4.4 million in
2007. Asia Pacific markets will be the most accepting of mobile TV.
In Japan, already more than 50 percent of the latest mobile phone
models feature mobile TV capability
The main challenges for mobile TV systems are to achieve a high
dynamic range, enhance system sensitivity for in-door reception or
tunnels, and to fulfill the stringent MBRAI (MultiBasic Rate
Interface) requirements. The Infineon BGA728L7 supports various
standards such as DVB-T, DVB-H, ISDB-T, MediaFLO, T-DMB, as well as
the emerging Chinese standards including CMMB, TMMB or DMB-TH. With
its high gain and excellent noise figure, the system sensitivity
can be considerably improved. By switching to low-gain mode with
input 1dB Compression Point of +3.5 dBm, the LNA can handle higher
input power level and therefore increase the system's dynamic range
by up to 20 dB. The fast switching time of 3.5 �s also allows it to
support time-slicing-based mobile TV systems.
"With the BGA728L7, Infineon expands its RF discretes portfolio
from the strong presence in stationary RF tuner frontend further
into the portable and mobile TV arena. The BGA728L7 is the first
mobile-TV LNA in the market that offers 1.8V capability and covers
such a wide range of frequencies," said Michael Mauer, Senior
Marketing Director Silicon Discretes at Infineon Technologies. "The
high-performance LNA demonstrates Infineon's deep expertise in RF
tuner applications as well as the company's leading position in RF
MMIC technology and design."
Technical Features at a Glance
The BGA728L7 supports a broad supply voltage range from 1.5 V to
3.6 V. At high-gain mode, it consumes about 5 mA current. The noise
figure is as low as 1.4 dB and the gain is about 16 dB with minimum
variation over the complete working frequency range. At low gain
mode, input IP3 (Third Order Intercept Point) is +16 dBm at a
current of only 0.5 mA. Due to the low voltage and low current
capabilities, BGA728L7 allows higher energy efficiency for portable
devices and extends their battery usage time. The on-chip 1 kV HBM
ESD protection simplifies the system ESD protection effort and
makes BGA728L7 very robust against ESD events during the assembly
process.
BGA728L7 integrates not only a high performance SiGe bipolar
transistor but also components such as active-biasing, feedback and
input/output matching circuits. BGA728L7 needs only three external
passive components compared to approximately five to ten additional
external components of current designs. As a result, system
designers of mobile phones and portable devices can easily use
BGA728L7 to realize a compact, low-power mobile TV design within
short time.
Availability, Package and Pricing
Samples of the BGA728L7 are available now, with volume
production to begin in July 2008. Infineon provides evaluation kits
to support customer designs. Pricing starts at USD 0.6 each for 10k
units. The BGA728L7 is shipped in a tiny leadless TSLP7-1 package
of only 2.0 mm x 1.3 mm x 0.4 mm in size.
