There was this fellow, Rudy Severns, who many years ago went on a speaking tour for International Rectifier to discuss “Hexfets,” their power MOSFETs, when that product line was still new. If memory ...

A novel full-wave rectifier turns an audio power amplifier into a simple modulator, that is then used to modulate an ...

This paper presents a highly linear and power backoff (PBO) efficiency enhanced Doherty power amplifier (PA). Our PA uses multigated transistors (MGTR) in the main PA and second harmonic control ...

With their low on-resistance, the transistors are excellent for demanding high-current applications, allowing significant improvements in both sound quality and efficiency of SounDigital's amplifier.

The amp features McIntosh’s new DualView Power Output Meter which stacks two meters in a single window. One of the meters displays the output of the 300-Watt vacuum tube section while the other ...

Efficiency indicates the conversion of DC power (Pdc) to output signal power (Pout). Power gain is defined as the ratio of power dissipated in the load (ZL) to the input power of the two-port network.

San Francisco, CA. Qorvo at IMS 2016 highlighted several new products and features. The company debuted six new 50-V GaN transistors and said that its QPD1000 15-W GaN on SiC ...

This paper presents a highly linear and power back-off efficiency-enhanced Doherty power amplifier (PA) fully integrated into CMOS. The proposed Doherty PA employs a transformer-based quadrature ...
