How to measure 5-nanosecond rise/fall time in pulsed power amplifiers

March 14, 2012

Rise/fall time is one of the key measurement parameters when designing, manufacturing or maintaining pulsed radar power amplifier systems, especially for wideband pulse power amplifiers. Learn how to achieve 5 nanosecond rise/fall time RF pulse measurement with Agilent Technologies 8990B peak power analyzer by reading this application note. This article also includes tips on how to consistently obtain accurate rise/fall time measurement results.

Planar Structures

March 1, 2012

Microstrip filters, planar antennas and other RF structures are solved efficiently using the planar Green's function. Only the stripline or antenna needs to be discretised with this method. Ground planes are treated implicitly by the formulation and do not add to the number of unknowns.

Windscreen Antennas

March 1, 2012

Antennas are increasingly incorporated into the windscreens of automobiles. FEKO has a special formulation to design the antenna and calculate the effect of the vehicle on the radiation pattern of the antenna.

Radiation Hazard Analysis

March 1, 2012

The combination of the integral equation (MoM) and the differential equation (FEM) solvers allows the efficient solution of real world radiation hazard problems e.g. calculating the effect of an antenna's radiation on humans sitting inside a vehicle. SAR is calculated according to international standards.
