Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

From #318 we have learned that a single 50x attenuator design does not cause the #316 issue, however the -3dB bandwidth of such an approach cannot reach our nominal spec of 500 MHz, nor a reduced ...

Offering fixed attenuation from DC to 60 GHz with low loss, Mini-Circuits’ BAT series of gallium-arsenide (GaAs) MMIC attenuators can handle up to 2 W of power. Provided in six-lead, QFN-style, ...

The Luxman L-509Z is the first to offer LIFES1.0 stages in both preamp and power amp and the first with LECUA-EX volume control. How many companies can boast being 100 years old? Denon, Yamaha, and ...

Attenuators are often defined as electronic devices that reduce the power of a signal without introducing significant distortion. While that’s not incorrect, it’s also not complete. For example, ...

An attenuator is a four-terminal, two-port network that reduces the amplitude of a signal without distorting its waveform. Attenuators are used in electronic instrumentation to precondition a signal ...

The $11,995 Luxman L-595A Special Edition Integrated Amplifier commemorates the 95th anniversary of the Japanese manufacturer in fine style. The new Luxman L-595A SPECIAL EDITION is a premium Class A ...

As applications ranging from communications to defense place new demands on tight amplitude control, microwave engineers increasingly rely on digital attenuators for precision and linearity.

Download this article in PDF format. The RF PIN diode as we know it today was invented by J. Nishizawa in 1950. Now, almost 70 years later, a new PIN diode concept—shielded-anode PIN diode (SAPIN)—has ...
