Graphene radio frequency receiver integrated circuit

Graphene radio frequency receiver integrated circuit.

Graphene has attracted much interest as a future channel material in radio frequency electronics because of its superior electrical properties. Fabrication of a graphene integrated circuit without significantly degrading transistor performance has proven to be challenging, posing one of the major bottlenecks to compete with existing technologies. Here we present a fabrication method fully prese...

Towards the Realization of Graphene Based Flexible Radio Frequency Receiver

We report on our progress and development of high speed flexible graphene field effect transistors (GFETs) with high electron and hole mobilities (~3000 cm/V·s), and intrinsic transit frequency in the microwave GHz regime. We also describe the design and fabrication of flexible graphene based radio frequency system. This RF communication system consists of graphite patch antenna at 2.4 GHz, gra...

Progress in Integrated- Circuit Horn Antennas for Receiver Applications

A receiver belonging to the family of integrated planar receivers has been developed at 90 GHz. It consists of a planar Schottky-diode placed at the feed of a dipole-probe suspended inside an integrated horn antenna. The measured planar mixer single-sideband conversion loss at 91.2 GHz (LO) with a 200 MHz IF frequency is S.3dB±0.3dB. The low cost of fabrication and simplicity of this design mak...

A direct-conversion receiver integrated circuit for WCDMA mobile systems

A prototype of a 3-V SiGe direct-conversion receiver integrated circuit for use in third-generation (3G) WCDMA mobile cellular systems has been completed. The goal of its design was to minimize current draw while meeting WCDMA receiver rf specifications with margin. The design includes a bypassable low-noise amplifier, quadrature downconverter, and first-stage variable-gain baseband amplifiers ...
