This paper presents a testbed design by using Software Defined Radio (SDR) and Radio-over-fiber (RoF) platforms for the next generation wireless access network. The proposed testbed supports concurrent multiservice transmissions, in which a heterogeneous network is emulated. The SDR is based on NI USRP RIOs, which generated both IEEE 802.11 and long term evolution (LTE) signals, and integrated with...
This paper presents the design methodology and implementation of a cascode low-noise amplifier (LNA) for 40GHz radio-over-fiber (RoF) system. The proposed LNA is implemented in 0.13µm CMOS technology. The single-stage LNA achieves a maximum measured small-signal gain of 8.87dB at 41.25GHz while consuming 18.3mW from a 2.0V supply. Measurement results also display a good input and output return losses,...
