Abstract
A resistive frequency mixing apparatus includes a first frequency mixer having a source follower FET, and a second frequency mixer having a common source FET. The resistive frequency mixing apparatus perform a frequency mixing of an RF depending on an LO signal to generate a down-converted IF signal when the RF signal is applied to the source follower FET and the LO signal is applied to the common source FET. Further, the resistive frequency mixing apparatus performs a frequency mixing of an IF signal depending on an LO signal through the use of the source follower FET to produce an up-converted RF signal when the IF signal is applied to the common source FET and the LO signal is applied to the common source FET.
