Wires and cables tend to behave as transmitting antennas. When troubleshooting a system for EMI, you must identify which cables have these undesirable “common mode” currents. Current probes let you ...

Several years ago, my team was given an assignment to measure RF radiation from Low Power CMOS ICs. In this article, I’ll describe the setup we designed and some of the problems we overcame to measure ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage – from design and prototyping to maintenance in the ...

Recently, a reader wrote to me seeking a copy of a paper on measuring the transient peak-to-average power ratio of DTV signals. So perhaps the topic of DTV signal power, which is so different from ...

Download this article in PDF format. Directional couplers are used in a wide variety of applications to sense RF power, and they may appear at multiple points in a signal chain. In this article, we ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage of a system’s lifecycle from the design and prototyping ...
