ALEXANDRIA, Va.—William H. Doherty was an engineer with Bell Telephone Laboratories in 1936 when he invented a circuit that used two tubes running in Class B configuration to act as a linear amplifier ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...

In just a few years’ time, so many things about wireless communication will be different from the way we know them today. Cellular networks, for example, traditionally made up primarily of larger base ...

Broadcast Solutions Electronics (Pty) Ltd. has launched a new 500 W FM transmitter/exciter using LDMOS amplifier technology. LDMOS amplifier technology offers exceptional efficiency in a Class C ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...
