We present an overview of solid-state integrated circuit amplifiers approaching terahertz
frequencies based on the latest device technologies which have emerged in the past …

We report on the design, fabrication, and testing of a new generation of all-solid-state
frequency-multiplied terahertz sources providing up to ten times more output power at room …

For wireless applications at millimeter-wave and terahertz frequencies, an amplifier module
with power combining is critical to boosting the output power of the solid-state transmitter …

We report on a compact high-power 510-560 GHz GaAs Schottky diode based frequency
tripler with enhanced power handling capabilities, showing a world-record measured peak …

Millimeter-wave and terahertz bands are very attractive for high-resolution radars and fifth-
generation communication and beyond; nevertheless, it is very challenging to achieve high …

In this paper, a new radial power combining/dividing method based on the circular sectoral
waveguide is proposed. By analyzing the basic characteristics of the circular sectoral …

We report on an ultra-compact 550 GHz Schottky diode based frequency tripler based on an
on-chip power combined structure that allows to integrate and combine four multiplying …
