AWR Corp. , a leader in high-frequency EDA, will award a free, fully-functional, one-year personal term license for its popular Microwave Office® and Visual System Simulator™ (VSS) software suites (including AXIEM™ 3D planar EM software) to the individual or team who wins the Sixth High Efficiency Student Power Amplifier...

Hittite Microwave Corp. , a supplier of complete MMIC-based solutions for communication and military markets, announces the release of a ceramic SMT packaged GaAs PHEMT SP4T (Single Pole, Four Throw) MMIC switch that is ideal for industrial sensors, test and measurement, microwave radio, military EW and space applications from...

Current versions of handsets do not seem to be getting smaller as they are already quite small. In fact, some handsets are becoming bigger to accommodate more functions desired by consumers, such as DSC, DVC, MP3, GPS, Internet access, Bluetooth, DTV, etc. Opposite to the earlier thought that fewer...

In full-duplex communication systems such as W-CDMA, a receiver’s tolerance to unwanted transmit signals, including a co-located transmitter, is significantly important since transmission and reception occur simultaneously. Since transmit signals can be as little as 30 MHz away in frequency from the receive signal, surface acoustic wave (SAW) filters...

In the last few years, the architectural design of satellite communications payloads has benefited from the view point of flexibility, from the adoption of Multiport Power Amplifiers (MPA). Multiport power amplifiers offer a means to combine discrete amplifiers in a way that is reconfigurable and will degrade gracefully in...

A novel design of a single-stage microwave distributed amplifier is presented in this article. The design is based on the use of a Chebyshev polynomial to express the transducer power gain of the distributed amplifier. The obtained amplifier provides a considerable increase in the bandwidth as compared to both...

Over the past decade, extensive research on broad dual- or multi-band antennas, with low-profile, lightweight, flush mounted and single-feed to fit the limited equipment space of portable wireless devices, has contributed to the development of modern communication technology. In the past, a whole host of dual- or multi-band planar...

Mimix Broadband’s XD1008-QH is a packaged broadband PHEMT distributed amplifier designed for medium power output over the 500 MHz to 32 GHz frequency range. It features gain slope adjustment, wide dynamic range gain control, 50 Ω match on the input and output ports, and robust protection against ESD damage....

It is obvious that the selection of the transistor for a power amplifier circuit is critical. However, it is often less obvious how the properties of the printed circuit board (PCB) can impact overall performance. The materials used to make the PCB can have an influence on a power...

Harris Corp. has received a follow-on $10.7 M order from the US Navy for 23 shipboard terminals that will provide personnel onboard frigates, access to the Internet, video and other high-speed, broadband services. These capabilities will help sailors stay better connected to their families and allow them to easily...
