Elbit Systems of America LLC was awarded a contract for TC-100L amplifiers as part of a weight reduction initiative for the US Army's OH-58 Kiowa Warrior. Deliveries of the TC-100L SATCOM amplifiers are scheduled for the fourth quarter of 2013.  

AWR has finalized the agendas and opened registration for the 11 remaining venues of its ADF European tour. ADF is a free and open event where designers of microwave and RF circuits and systems such as monolithic microwave integrated circuits (MMICs), RF printed circuit boards (RF PCBs), and LTE communication systems can network, share useful information and resources pertinent to high-frequency design, and collaborate on industry issues and trends.

Fujitsu Laboratories Ltd. announced the development of circuit technology that enables industry-leading electrical efficiency (the ratio between output power and consumed power) for wireless transmission power amplifiers used in radio-frequency wireless devices, such as mobile phone base stations.

TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, announced the release of new gallium nitride (GaN) transistors that offer superior gain, thermal management and efficiency for commercial and defense RF amplifier designs.  

A1 Microwave has recently developed a range of Ka-Band combiners for satellite communications transmitter applications. The 2 and 4 way combiners are used to combine the output power levels produced from transmitter amplifiers to achieve an overall high output level.

Rohde & Schwarz has enhanced its new R&S SMW200A high-end vector signal generator by adding the R&S SMW K540 option for envelope tracking. This option enables quick and easy testing of envelope tracking power amplifiers for smartphones, base stations and tactical radios.   

Skyworks Solutions Inc. introduces four linear power amplifiers for LTE and WCDMA applications. The fully matched surface mount SKY66001-11 (2110 to 2170 MHz), SKY66002-11 (1900 to 2025 MHz), SKY66005-11 (850 to 920 MHz) and SKY66008-11 (900 to 990 MHz) modules meet the stringent spectral linearity requirements of femtocell applications with high power-added efficiency. An integrated directional coupler eliminates the need for any external coupler.

If you are assessing the power conversion efficiency of your power amplifiers, you are probably making power-added efficiency (PAE) measurements. Most PAE test setups use multiple instruments – such as RF power meters, digital oscilloscopes and DC power analyzers – to calculate RF voltage and current measurements.

Mini-Circuits is pleased to contribute to the 2013 IEEE Conference on Microwaves, Communications, Antennas, and Electronic Systems(COMCAS) as a platinum sponsor. Representatives from Mini-Circuits and MCDI, Mini-Circuits’ new distributor in Israel, will be exhibiting at Booth 31 with a showcase of its rapidly growing line of portable test equipment and other selected new products.

NuWaves Engineering, an international Radio Frequency (RF) and Embedded Systems solutions provider, announces it has achieved both ISO 9001:2008 and AS9100:2009 Rev C certifications for its Quality Management System by EAGLE Registrations Inc. With an effective date of August 15, 2013, the registration is valid for three years and its scope includes research and development as well as design and production of RF systems and subsystems.
