Abstract
A new current-sensing integrated power control design method is invented. Based on this method, a GaAs (Gallium Arsenide) HBT (Heterojunction Bipolar Transistor) power amplifier MMIC (Monolithic Microwave Integrated Circuit) can be implemented with integrated current-sensing power control function. This MMIC provides a low-cost solution for GSM handset dual-, triple- or quad-band RF power amplifier module as well as other mobile communication devices.
