A new uniplanar architecture of subharmonically pumped balanced mixer is proposed and developed for low-cost broadband design of millimeter-wave transceiver. Our theoretical and experimental studies carried out over Ka-band show that the new mixer has a conversion loss comparable to the conventional balanced fundamental harmonic mixer. They demonstrates, on the other hand, unparalleled advantages such as very high isolation between ports, wide operating bandwidth, excellent suppression of unwanted LO/RF harmonics and mixing signal components, and also less demand on the LO source.read more
