A high frequency amplifier includes a package substrate, an amplifying active device disposed on a top surface of the package substrate, a transmission line connected to the amplifying active device and transmitting a high frequency signal, a surface mounted device (SMD) component shunt-connected at a first end to the transmission line, a SMD component terminal connected to a second end of the SMD component and partially exposed at a back surface of the package substrate, and an external terminal partially exposed at the back surface of the package substrate and connected to a first end of the transmission line, opposite a second end of the transmission line that is connected to the amplifying active device.
