Today Wireless communications has stepped forward and made the announcement that researchers have created a functional integrated circuit. The size of circuit is smaller than a grain of salt.

Yu-Ming Lin, an IBM researcher who has helped in leading the circuit has said that the circuit is a broadband frequency mixer.

The newest mixer comes in the list of the most fundamental and important circuits. It is specially known for wireless communication devices and equipment.

The mixers will be able to convert low-frequency audio signals into high-frequency signals. The signals will be transmitted wirelessly. The new circuit is made of the Nobel Prize worthy crystalline material, graphene. This material is made with a single layer of carbon atoms.

In past few years the research community has been looking out graphene as it is the strongest crystalline material used widely. It has a feature that can be stretched like rubber. In addition it is an excellent conductor of heat and electricity. Other features are that it has lighter and cheaper body armour, touchscreen displays and chemical sensors.
