Although the modular Portable Mixer design available on these web pages has become a hit for many amateurs, some correspondents required a much simpler device, mainly for mixing mono signals. This ...

Wireless communications took a small leap forward today with the announcement that researchers have created a functional integrated circuit smaller than a grain of salt. The circuit is a broadband ...

Researchers at Chalmers have for the first time demonstrated a novel subharmonic graphene FET mixer at microwave frequencies. The mixer provides new opportunities in future electronics, as it enables ...

This FET audio mixer is an example of FET’s versatility. FETs are originally designed for high frequency applications but they can be used for audio frequencies and in fact they perform excellently in ...

CMOS mixers are integral components in modern radio frequency (RF) circuit design, enabling frequency conversion in wireless systems while prioritising low power consumption. Recent progress in ...

Graphene circuit: This integrates a graphene transistor (inside the red box) with two other elements, called inductors, on a single chip. The black devices at the sides and top of the image are ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

This paper presents two approaches to improve the performance of RF low noise amplifiers (LNAs) and downconversion mixers. One approach is for noise enhancement and the other is for improving flatness ...
