An integrated double balanced mixer on multilayer liquid crystalline polymer (M-LCP) based substrate

This paper presents the design of an integrated double balanced mixer on a novel multilayer LCP based substrate. Low-loss lumped and distributed components were realized on a 3-layer LCP stackup, which were then used for the design of novel wideband baluns. A double balanced mixer for WLAN applications was realized using embedded baluns in the substrate. The mixer exhibits 5.1-8.6dB conversion loss over a frequency band of 3.5-5.5GHz.
