In a 50 system, the characteristics of a microwave transistor measured at 1.3 GHz is
shown as the following.
Design a high-frequency amplifier with microstrips. The PCB material has an , thickness h=1 mm. The velocity factor is . The microstrip geometry is w/h=0.94 for a 50 line. At a frequency of 1.3 GHz, the guided wavelength is mm.
The transistor is unconditionally stable.
