Adaptive Dummy-gate (field-plate) Bias Technique for RF LDMOSFETs (Technology#: 090506-01)
This invention uncovers a method of applying a suitable modulated bias to the dummy-gate (or field-plate) in RF-LDMOSFETs to improve the efficiency and output power. Initial tests of this technique show a 60% improvement in the maximum output power, and a 10% improvement in the efficiency of the device. The increase in output power will translate...
