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 ...

There is a basic method for measuring high-frequency power using a power meter and power sensor (Fig. 1). The power sensor converts high-frequency power to a dc or low-frequency signal that the power ...

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 ...

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 ...
