Disruptive TRX design for the D-band
Résumé
This paper presents an architecture for broadband wireless transceivers operating in the D-band with the aim of covering tens of GHz of band over the air with a limited bandwidth per channel at the baseband. The main idea is to combine several baseband channels in a multi-channel radio-frequency (RF) signal. This is in contrast with the more conventional trend of using a single channel from baseband (or intermediate frequency) to RF. In this work, the main challenges introduced by this type of broadband channel bonding architecture are analyzed and some solutions are provided. A prototype implementation in CMOS 45 nm RFSOI technology and low cost PCB technology is used to illustrate the potentialities of this disruptive approach.
