The input to the circuit is connected to an USRP through an SMA cable. The output is connected to an half-wavelength (1.5m) dipole antenna. The input power is in the order of 50 to 100mW. The output which is close to 2W in my simulations is about the same power as the input in the real world. What is causing this?
Edit: I am actually using RD06HVF1 transistor. I am using the spice model for RD06HHF1 as the specs are identical.
