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 ...

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 ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

What is a chopper-stabilized operational amplifier (op amp)? Chopper-stabilized amps constantly correct low-frequency errors across the inputs of the amplifier. This makes them attractive alternatives ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Reflective Semiconductor Optical Amplifiers, also known as RSOAs, are high-performance, low-cost transceivers used for data amplification and modulation in radio over fiber systems, full-duplex optic ...

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 ...

$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 ...
