ABSTRACT:
A compact amplifier output bias circuit is used as a broadband harmonic termination. The bias circuit is adapted as a harmonic termination circuit to produce an effective low impedance or act as a load at the signal harmonic frequencies while having the capability of supplying DC power to the amplifier stage, optionally, if needed. A pi network is coupled to an active device output and provides a low impedance at frequency bands above a frequency band of operation while allowing DC bias to be appliable to the active device output.
