Abstract: Provided is a FET resistive frequency mixing device having improved RF-LO and IF-LO isolations. The frequency mixing device includes: a field effect transistor (FET), a local oscillation matching circuit connected to a gate of the FET to transfer a local oscillation signal to the gate of the FET, a gate biasing circuit connected to the gate of the FET, a radio frequency (RF) matching circuit having a first terminal connected to a drain side of the FET and a second terminal serving as a RF terminal to receive or output a RF signal, an intermediate frequency (IF) matching circuit having a first terminal connected to the drain side of the FET and a second terminal serving as an IF terminal to receive or output an IF signal, and a series resonance circuit providing a path from the drain of the FET to ground for the local oscillation signal.

Abstract: Provided is a microwave power combiner. A 2-way microwave power combiner includes a first input stage and a second input stage each through which a microwave signal is input; a first output stage through which a sum signal between the microwave signals is output, in response to the microwave signals input through the first input stage and the second input stage having the same phase; and a second output stage through which a difference signal between the microwave signals is output, in response to the microwave signals input through the first input stage and the second input stage having different phases. The first input stage, the second input stage, the first output stage, and the second output stage are connected using a suspended line that includes a conductive line positioned on a dielectric layer provided between air layers.
