Houston, Texas—Mimix Broadband, Inc. announced the XP1003 GaAs monolithic microwave integrated circuit (MMIC) power amplifier optimized for linear operation. This two-stage power amplifier is well ...

Envelope tracking (ET) power amplifiers and supply modulators represent a pivotal advance in modern radio frequency (RF) design, particularly for wireless communications. These systems dynamically ...

RF-engineering company Nujira has extended the reach of its efficiency-boosting technology for power amplifiers into the handset. The company has until now focused on the infrastructure side of ...

June 3, 2009 We’ve been living in a digital age for a while now and many of us access all our music from digital formats like CD and MP3. But has anyone managed to perfect a purely digital amplifier?

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 ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

The third edition of IEC 61000-4-3, published in 2006, has mandated changes in some key areas that may require the replacement of your radiated immunity test amplifier. Along with extending the test ...

During broadcast radio’s first decade, little thought was given to transmitter efficiency. Main concerns of the industry were availability of broadcast spectrum (sound familiar?); keeping transmitter ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

Sweden's Marten is well-regarded for its high-end speakers and takes a fair amount of pride in their audiophile-pleasing performance. So it comes as no surprise to learn that the company has decided ...

$7,200 is a crazy amount of money for any audio component but is the Aavik Acoustics I-180 Integrated Amplifier worth it? The Danish high-end audio manufacturer Aavik was nice enough to send me three ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...
