This work presents a continuously variable SIW phase shifter based on liquid-crystal technology with a maximized figure of merit and adequate biasing. The proposed design operates efficiently within t...
A multi-functional filtering amplitude/phase circuit (MFAPC) with tunable frequency is proposed in this paper. It comprises a frequency reconfigurable filtering power divider (RFPD) integrated with a ...
To extend SI-traceable calibration for coaxial measurements up to 165 GHz, seven calculable offset short standards in the 0.8 mm coaxial system are used. The standards are calculated based on dimensio...
This paper introduces a novel wideband active load-pull system leveraging vector network analyzer (VNA) frequency extenders (FXs) for precise device characterization at millimeter-wave frequencies. At...
Zero-IF transceiver systems use digital compensation techniques to mitigate communication distortions and improve performance. However, receiver compensation models generally struggle to simultaneousl...
We present in this paper the characterization of state-of-the-art photonic microwave oscillators by using a commercial cross-correlation-based phase noise analyzer and two auxiliary commercial oscilla...
InP heterojunction bipolar transistor (HBT) technologies have significant power gain at frequencies greater than 100-GHz. Power amplifiers and integrated circuits have been demonstrated with state-of-...
This paper presents a 300-GHz-band power amplifier (PA) module implementing a PA integrated circuit (IC) fabricated in 250-nm indium phosphide (InP) double-heterojunction bipolar transistor (DHBT) tec...
This paper reports on an eight-channel active phased array monolithic microwave integrated circuit (MMIC) which includes on-chip vector modulators, power amplifiers, and antennas, all operating around...
This paper introduces a wideband distributed amplifier (DA) using Indium Phosphide (InP) heterojunction bipolar transistor (HBT) technology that achieves a 208 GHz bandwidth. The DA comprises eight un...
