A Millimeter-Wave Front-End for FD/FDD Transceivers Featuring an Embedded PA and an N-Path Filter Based Circulator Receiver

This work presents an ultra-compact single-antenna FD/FDD transceivers front-end. It comprises a nonreciprocal circulator, RX, and an integrated power amplifier (PA). In the proposed circulator, we devise a ring quarter-wave transmission line topology with adjusted characteristic impedances to improve TX-to-antenna insertion loss and TX-to-RX...

Post-war duplex housing in courtyard configuration: Transformation towards adaptive neighborhoods: Cas Roland Holstbuurt

The graduation studio ‘Housing as heritage’, within the chair of Restoration, Modification, Intervention and Transformation (®MIT), deals with complex social issues and degeneration processes of post-war housing neighborhoods. This graduation project in particular aims at a strategy for phased revitalization of post-war ground bound duplex...

Full-Duplex CMOS Duplexer: Passive self-interference cancellation

To accommodate the growing demand for wireless communications, new techniques are required to increase throughput of wireless networks. One technology aiming to increase the spectral efficiency of wireless devices is full duplex (FD) radios. These systems are capable of single carrier transmission and reception and could ideally double the...

Stirling Solar cooling in office façades

The requirements, comfort needs and expectations for facades have increased, so has the need for energy efficient design. Present climate systems are using a lot of energy, especially to control heat and cooling loads. The cool load and solar power often occur at the same time and an increase of solar power often increases the cool load of a...
