Precise device characterization is the starting point of any good circuit design. This task can be particularly challenging when the device is a high power transistor having low input and output impedances. For devices working only under pulse conditions, specific test benches exist 1 but are rather complicated and...

As is well known, there are two general types of altimeter systems - a pulse radar altimeter and a frequency modulated, continuous wave (FM-CW) radio altimeter. Aircraft radio altimeters typically operate at altitudes from 0 to 8000 feet utilizing separate antennas for transmit and receive. Such radio altimeters have...

Welcome to Philadelphia, home of the 2003 International Microwave Symposium! The fifth-largest city in the United States and the second largest on the East Coast, Philadelphia (known from June 8-13, 2003 as Microwave Metropolis) is one of the world's most dynamic destinations. In Philadelphia, you will be at the...

This year the IEEE MTT-S International Microwave Symposium (IMS) and Exhibition will be held in Philadelphia, PA at the Pennsylvania Convention Center. Although the MTT-S Symposium was hosted by the Philadelphia Chapter of MTT-S at Cherry Hill, NJ in 1976, this is the first time the IMS will be...

Philadelphia, nestled between New York City and Washington, DC, has at times been overlooked or forgotten when noting major US cities. But since it is one of America's oldest cities (1682), Philly has had, I guess you could say, a little head start over other towns. No wonder she...

This article is intended to provide insight into the effective operation of variable gain amplifiers (VGA) in automatic gain control (AGC) applications. Figure 1 is a general block diagram for an AGC loop. The input signal passes through the VGA to produce the output level to be stabilized. The...

Assessing mixer spurs reliably can enable first-cut success in communication hardware design with reduced development time and product cost. The tools used to determine these spurs must be able to manipulate LO, RF and IF frequencies concurrently over their continuous bandwidths. These tools can be either standard graphical charts...
