RAYMOND, ME. — Sinclair subsidiary Dielectric has developed a new green, cost-reducing load solution featuring a closed-loop cooling system, a new advancement that protects RF System components from ...
Calculating the load impedance and power consumption at high frequencies in RF circuits is a tedious task. This Design Idea describes a VI (virtual instrument) that provides an easy way to quickly and ...
Figured this was the best place to put it.<BR><BR>I'm making 50 ohm RF dummy load with resistors. So I'm using 0.5W metal film resistors in parallel, a fair few of them.<BR><BR>I have 49.9 ohms ...
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 ...
This method has been refined over the years, and NIST reports that they can now calibrate transfer standards with an uncertainty of 0.67% [3][8] for 100 W measurements below 1 GHz. This uncertainty ...
