The National Semiconductor LMV225 is a linear RF power meter IC in an SMD package. It can be used over the frequency range of 450 MHz to 2000 MHz and requires only four external components. The input ...
Modern high-performance transmitters require accurate monitoring of RF power, because most cellular standards depend on strict power- transmission levels to maintain an effective network. Regulation ...
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 ...
How your use of power sensors and spectrum analysers can influence outcomes in RF and microwave power measurements, writes Giovanni D’Amore of Keysight Technologies. The ability to make consistent ...
In day-to-day use, electromagnetic field (EMF) meters are used to diagnose problems with electrical wiring and power lines and to get readings on working appliances. On television, professional ghost ...
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 ...
Power sensors and signal processing A typical power sensor and meter includes a sensor element followed by analogue and digital signal-processing components, as shown in Figure 2. The sensor element ...
