The model dB-3814 microwave power module (MPM) from dB Control Corp. boasts 1 kW peak output power from
15 to 18 GHz at 7% maximum pulse duty cycle. Ideal for airborne synthetic aperture (SAR) and multi-mode radars,
the MPM can operate at altitudes to 40,000 ft, and can handle operating temperatures from -40 to +85°C. It is
designed for low phase noise and excellent phase stability. Meppalli Shandas, dB Control Vice President of
Technology and Business Development, explains: “MPMs used onboard military airborne systems must be compact
and low weight while providing maximum power and a high duty cycle. The dB-3814 provides more than twice the
output power of comparable MPMs, and does so over a wider frequency range…Considering that we’ve increased
the bandwidth and power without increasing the payload, this new MPM is sure to be in demand.” The new MPM
weighs 14 lbs. and measures 12 x 10 x 3 in. It employs a miniature traveling-wave tube (TWT) with periodic-
permanent-magnet (PPM) focusing combined with solid-state monolithic-microwave-integrated-circuit (MMIC)
amplification for high gain. For more information, click here.

Numerous key players in the satellite communications (satcom) equipment and services market—including Newtec,
Cisco, Arabsat, SES, and Thomson Video Networks—have made the case that it is now time to consider an upgrade
to the DVB-S2 satcom standard. Because of the increasing use of satcom technology for data transmissions, including
for Internet Protocol (IP) services, the goal of any standard upgrade is to improve satellite efficiency for high-speed IP
trunking and backhauling. Proposed changes would include the opportunity to perform optimization per application, an
increased number of modulation and coding schemes, such as 64APSK, and greater choices for forward error
correction (FEC) in these satcom systems. For their part, Newtec is unveiling its Clean Channel Technology™
for improved satellite efficiency, especially for IP use. For more information, click here.

Models PAN1327 and PAN1317 from Panasonic are compact Bluetooth modules that allow Bluetooth functionality to
be added to a host of portable and battery-powered products. The two modules combine both Dynastream’s ANT
wireless protocol and Bluetooth connectivity for reliable low-power, short-range wireless connectivity. The protocol is
ideal for personal area networks (PANs) and wireless sensor networks (WSNs). Both modules feature compact
footprints, including antenna, of only 9.0 x 9.5 x 1.8 mm for the PAN1327 and 6.5 x 9.0 x 1.7 mm for the PAN1317
and are designed to operate on supplies of +1.7 to +4.8 VDC. The modules are based on the model CC2567
Bluetooth chip from Texas Instruments and are ideal for a wide range of applications, including industrial
sensors, toys, electronic entertainment devices, health monitors, and alarm systems. They provide +10 dBm transmit
power and achieve -93 dBm receive sensitivity and are Bluetooth, FCC, IC, and CE certified.
+1.7 to +4.8 VDC supply. To learn more, click here.

The M83401 line of single-in-line, thin-film resistor networks from Vishay is
available with three to nine resistors in 6-, 8-, and 10-pin low-profile configurations, designed and manufactured to
outperform all the requirements of MIL-PRF-83401 R, V, and H characteristics. These resistor networks feature low
absolute temperature coefficient of resistance (TCR) of ±25 ppm/°C, TCR tracking of 5 ppm/°C,
and resistance tolerances within ±0.05%. These type RZ070, RZ080, RZ090, RZ210, RZ220, and RZ230
device features 100 % burn-in screening for increased reliability in demanding military applications over operating
temperatures from -55 to +125°C. The resistor network features a rugged, molded thermoset plastic construction
with gold-plated copper alloy leads. The leads are attached to the metalized alumina substrates by thermocompression
bonding.

Suitable for commercial and military communications systems, model LX-7800 frequency synthesizer from EM Research provides stable output signals at 7800 MHz when operating
with a 100-MHz reference oscillator. It controls harmonics to better than -20 dBc and spurious levels to better than -
60 dBc. Phase noise is better than -92 dBc/Hz offset 10 kHz from the carrier and
better than -98 dBc/Hz offset 100 kHz from the carrier. The frequency synthesizer, which delivers +8 dBm output
power, draws 200 mA from a +5-VDC supply. It is designed for operating temperatures from -30 to +70°C. It is
supplied in a compact housing measuring 0.75 x 0.75 x 0.15 in. (19.0 x 19.0 x 3.8 mm) with SMA connector.

Motorola won an award from the Bluetooth Special Interest Group (SIG)
last month at the 2012 Consumer Electronics Show in Las Vegas, NV. The firm’s MOTOACTV, which allows wireless
connectivity between health and workout monitors and smartphones, was named the overall winner for best Bluetooth
product. According to Michael Foley, Ph.D., Executive Director of the Bluetooth SIG, “Our overall winner this year,
the MOTOACTV, exemplifies exactly what this new generation of Bluetooth enabled products are about. The
MOTOACTV can support low energy devices, like a heart rate monitor, while still having all the functionality Bluetooth
technology is known for—transferring data to your phone, streaming music through your wireless ear buds and keeping
your hands-free.” Suke Jawanda, Bluetooth SIG Chief Marketing Officer, adds the following: “The MOTOACTV
was one of the first Bluetooth Smart devices to come to market, allowing users to enjoy a completely wireless workout
and then to view workout history through a Bluetooth enabled app on their Droid RAZR smart phone.” For more on
MOTOACTV, click here.

Third-order-intercept (TOI) point is a parameter used to evaluate the linearity of components utilized in applications where nonlinear effects can cause distortion—for example, in digitally modulated signals. This measurement can be challenging, as uncertainties vary based on a spectrum analyzer’s settings. In this web-exclusive article, Agilent Technologies' Bob Nelson investigates whether a better way exists.
