Real-time
spectrum analyser reveals multiple perspectives on combo device
behaviour
Dean Miles, Tektronix
Over the course of two earlier articles in this series, we have
examined the architecture and functions of real-time spectrum
analysers (RTSA), a versatile class of benchtop RF instruments
designed to address today's transient and complex RF phenomena. In
this third and final article we will discuss the potential of the
RTSA approach for solving problems in wireless "combo"
devices.
First
time right design of Class A power amplifiers using the novel power
parameters
Ivan Boshnakov, Aerial Facilities
This article discusses and describes a procedure of how to design RF/
microwave Class A power amplifiers in a very efficient and highly
accurate manner when the novel quasi-linear transistor power
parameters are used. As in the earlier article, two software programs
are used in conjunction and interaction: a specialised RF/microwave
amplifier design software tool and a general purpose simulator (nodal
analysis program). This time the simulator is not used for its
nonlinear analysis capabilities but mostly for its integrated layout
EM simulation capabilities.
