GaAs is In but Silicon is Not Out

Aggressive pricing has boosted demand for GaAs-based wireless power ICs. Today, even some moderately priced GSM handsets are using GaAs power amplifiers. Another trend in handset design is the increased reliance upon power modules. Modules greatly simplify design of notoriously complex power amplification circuits. While the market for power...

Effects of Grounding and Bias Circuit on the Performance of High Frequency Linear Amplifiers

The design of a high frequency amplifier is normally based on the S-parameters supplied by the manufacturer of the active device. However, in a practical design, these parameters are affected by the DC bias network and the grounding of the active devic...
In the design of high frequency power amplifiers, one of the parameters is the stability of the active device. The stability of the active device is determined by the Rollet stability factor K. If K > 1, then the active device is unconditionally stable and the design of the...
