Workshops & Courses RF Components and Systems for Short Range Wireless Transmission Topics : Enables engineers to estimate the system requirements of wireless short range applications and to design a data transmission system in an unlicensed frequency band. The tools most frequently used in RF engineering are introduced using...

News From Washington FCC Initiates Proceeding to Promote Commercial Development of mm-wave Spectrum The Federal Communications Commission (FCC) has initiated a proceeding to examine methods to promote the commercial development and growth of spectrum in the 71-76 GHz, 81-86 GHz and 92-95 GHz bands. Non-government users have never before...

International Report Thales Launches CATS French-based contractor Thales Airborne Systems used the 22-28 July Farnborough International Air Show to showcase its latest airborne electronic warfare (EW) product, the Compact Airborne Threat Surveyor (CATS). Operating within the E- to K-band (2 to 40 GHz) frequency band, CATS is a combined...

RF Technologies for Low Power Wireless Communications Tatsuo Itoh, George Haddad and James Harvey, Eds. John Wiley & Sons Inc. 468 pages; $84.95 ISBN: 0-471-38267-1 Several years ago a program in low power electronics initiated by the Army Research Office focused on addressing the issue of RF and microwave...

A new surface-mount technology (SMT)-packaged power amplifier has been introduced for wireless communications applications, including millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), satellite communications (SATCOM) and very small aperture terminal (VSAT) use. The model XP1000P1 GaAs MMIC surface-mount power amplifier is a two-stage amplifier optimized for linear output...

To meet the rapidly increasing demand for advanced microwave components and antennas in wireless terrestrial and satellite-based communications, accurate and efficient CAD tools are critical. Due to efforts made during the 1990s - the decade of global 3D electromagnetic (EM) field solvers - the task of accurate analysis of...

Test applications that require microwave power from 1 to 18 GHz are usually addressed by two amplifiers, a solid-state unit to cover the low frequency range and a traveling-wave tube amplifier (TWTA) for the higher range. The input signal must be switched between the two amplifiers and, if there...

With the steady improvements in tracking radar technologies over the past twenty years, the diameter requirements for antennas has been reduced to match the improvements in transmitter power and receiver sensitivity. This has led to a need for shorter feeds for use in Cassegrain configurations. Antenna feeds have recently...

By using impedance or admittance inverters, microwave bandpass filters can be designed more conveniently with only one kind of resonator. Theoretically, the inverters have to be frequency independent. However, this is not true for practical cases. One of the most serious degradations in frequency response of a bandpass filter...
