Broadband Can Flourish Without Power Lines

Demand for broadband services, including high-speed data and video, is
increasing steadily in the United States, prompting the installation of fiber-
optic cables, wireless networks and, in some cases, modulation of power lines.
Although at least one study (see news below) points to huge growth for the
broadband over power line (BPL) approach, it is hardly the most optimum means of
delivering broadband services.

While it appears practical, with so much power line infrastructure already in
place, the approach essentially transforms those power lines into long,
radiating antennas, creating radio interference for numerous existing
communications systems, including amateur ("ham") radios. Other approaches, such
as WiMAX, can provide those broadband services without the interference, and by
leveraging existing cellular infrastructure such as towers and cell sites. For
more on the realities and problems of BPL technology, visit the ARRL amateur
radio site at www.arrl.org.

Research Firm Applauds RFMD's GaN Strategy

Research and consulting firm Strategy Analytics has concluded that the gallium
nitride (GaN) device activities of RF Micro Devices represent a coherent
business strategy for the company. Their report, "RF Micro Devices Adds GaN
Foundry Strategy To Maintain Leadership in Compound Semiconductor Industry,"
points to orders from the military sector as helping to offset cyclical sales in
the commercial sector. The research firm forecasts that the market for GaN
devices will grow at a compound annual growth rate of 151 percent through 2010,
with military applications accounting for 50 percent of the GaN device demand.

Broadband Over Power Lines To Outpace Cable

Tremendous growth is projected in the number of US households receiving
broadband communications services by means of broadband over power line (BPL)
technology, according to a report from Parks Associates. The report, "FTTx and
BPL: Analysis and Outlook," projects that BPL users in the US will increase from
400,000 in 2007 to 2.5 million by 2011. According to the report, BPL technology
will outpace cable and DSL technologies over the next five years.

Rodelco Develops X-Band Receiver

Rodelco Electronics has designed and manufactured a custom airborne receiver
with dual-downconversion superheterodyne architecture for use at X-band
frequencies. The receiver includes a variety of precision components, including
an attenuator, low-noise amplifier (LNA), RF bandpass filter, local-oscillator
(LO) filters, ceramic bandpass filters for the first intermediate frequency
(IF), and lumped-element bandpass filters for the second IF. The airborne
receiver achieves better than 70 dB conversion gain with spurious suppression of
better than -90 dBc.

Motorola Invests in AMIMON's WHDI Technology

Motorola, through its Motorola Ventures venture capital arm, has made an equity
investment in AMIMON, Inc., a developer of semiconductor solutions for wireless
high-definition (HD) video transmissions. AMIMON's wireless high-definition
interface technology enables wireless transmission of uncompressed
high-definition video streams in the unlicensed 5-GHz band. According to Dr.
Yoav Nissan-Cohen, Chairman and Chief Executive Officer of AMIMON, "The
investment from Motorola will fund our plan to set WHDI as a new industry
standard for connecting high-definition video sources to displays wirelessly."

Compact Antenna Covers Two Bands

The model UFDD224580303PT ceiling-mount dual diversity omnidirectional antenna
is designed to cover the wireless-local-area-network (WLAN) bands at 2.4 to 2.5
GHz and 4.9 to 5.9 GHz. The flat antenna employs vertical linear polarization to
achieve 3 dBi nominal gain in both bands with better than 25 dB isolation
between frequency bands. The horizontal beamwidth is truly omnidirectional, at
360 deg., while the vertical beamwidth is 55 deg. at 2.4 GHz and 40 deg. at 5
GHz. The antenna is designed to handle 25 W maximum input power at either
frequency band.
