Hi ,
i want to design a power driver at 900 MHz. For this application i chose NPTB00004 transistor from maccom. In the datasheet they provide optimum load impedance and optimum source impedance for maximum power.
**broken link removed**
I designed a matching circuit for input and output as per the datasheet value for 900 MHz
**broken link removed**
From the Sparameter model from the website i simulated the amplifier but the S parameter values are at 900 MHz is not less than -10 dB. After analyzing stability parameter K , the amplifier is not stable in that frequency.
**broken link removed**
please help me to find proper design for the power amplifier ?
