eGaN FETs for Class A RF Amplifiers

High frequency enhancement mode transistors, such as the EPC8000 series eGaN® FETs from EPC, have been widely available since September 2013 and enable simplified designs at RF frequencies. In this installment, we present the RF characteristics of the EPC8000 series devices and show their implementation in a pulsed class A amplifier. The amplifier is pulsed to allow operation within the thermal operating limits of the device, since RF device power dissipation is typically on the same order of magnitude as the RF power delivered, unlike switching devices, such as the EPC8000 series, ...

GaN manufacturing leverages the installed silicon supply chain

Hundreds of billions of dollars have been spent to make the silicon technology supply chain incredibly efficient. How can emerging, high performance GaN transistors compete against this huge installed base of silicon-based production? Simple, the production of GaN transistors leverages the installed silicon supply chain, which significantly lowers the cost of GaN transistors!
