Measuring RF Power Sensor Nonlinearity RF power sensor linearity is a commonly misunderstood topic. To obtain the most accurate power measurements, though, you need to understand what linearity is, ...

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 ...

In August, this column took up some aspects of the measurement of DTV transmitter power output. You might wonder why I used the phrase "DTV transmitter power output" instead of "effective radiated ...

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 ...

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 ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

The detector gives precise, stable, and accurate control of power over a wide dynamic and temperature range. The LMV221 handles multiband frequencies from 50 MHz to 3.5 GHz with 40 dB of dynamic range ...

RF power sensor linearity is a commonly misunderstood topic. To obtain the most accurate power measurements, though, you need to understand what linearity is, the sources of nonlinearity, and how to ...
