Multilayer Integration of Low-Cost 60-GHz Front-End Transceiver on Organic LCP

This letter presents a low-cost and lightweight transceiver with RF front-end components integrated on multilayer organic liquid crystal polymer (LCP) substrate for 60-GHz wireless communication applications. Two embedded dual-mode filters with an insertion loss of 3.1 and 2.4 dB are included, while they are designed to improve the isolation between the transmitting and receiving modes. A package-integrated high-gain vertical dipole is used for the radiating element with orthogonal polarization between the transmitting and receiving modes. The transceiver module after integrating a power amplifier (PA) and a low noise amplifier (LNA) for each mode has a measured gain of 12 dBi for the transmitting mode at 61.5 GHz and 22 dBi for the receiving mode at 66 GHz.
