摘要:
A high frequency power device (100) is described comprising a high frequency power transistor (102) having a first main electrode, a second main electrode acting as output electrode and a control electrode, and an output compensation circuit (104) for compensating parasitic output capacitance of the transistor (102). The output compensation circuit is physically positioned relative to the transistor such that a shorter bond wire between the output electrode of the transistor and an output lead of the high frequency power device is obtained. The output compensation circuit (104) therefore is physically located in between an input lead (108) of the high frequency power device (100) and the transistor (102). The inductance introduced by the bond wire Lcomp from the output compensation circuit (104) to the output electrode of the transistor (102) can be used as a feedback signal. Selection of the mutual inductive coupling between the bond wire LcOmP and a bond wire connected to the pre-matching circuit (106) allows to further optimize the properties of the high frequency power device.

一种高频功率器件(100)被描述为包括具有第一主电极,作为输出电极的第二主电极和控制电极的高频功率晶体管(102)和用于补偿寄生输出的输出补偿电路(104) 晶体管(102)的电容。 输出补偿电路相对于晶体管物理定位,使得在晶体管的输出电极和高频功率器件的输出引线之间获得较短的接合线。 因此,输出补偿电路(104)物理地位于高频功率器件(100)的输入引线(108)和晶体管(102)之间。 由接合线Lcomp从输出补偿电路(104)引入到晶体管(102)的输出电极的电感可以用作反馈信号。 选择接合线LcOmP和连接到预匹配电路(106)的接合线之间的互感耦合允许进一步优化高频功率器件的特性。
