This study introduces a novel miniature Magnetostatic Wave Filter (MSWF) based on micromachined Yttrium Iron Garnet (YIG) with meander line transducers. The MSWF achieves a low insertion loss of 2.1–3...
In this paper, a Ka-band 256-QAM ninefold sub-harmonically injection-locked (SIL) I/Q modulator using frequency-tracking loop (FTL) and pulsed oscillator (P-OSC) is proposed using 90-nm CMOS process. ...
This paper presents a Ka-band high power and low phase noise GaN oscillator with a 2nd-order folded open loop filter employed in the feedback loop. The concept of complex quality factor (Qsc) is emplo...
This paper proposes an ultra-low phase noise negative-resistance substrate integrated waveguide (SIW) oscillator. The SIW bandstop filter, which offers a high unloaded quality factor (Qu) with selecti...
Accurate microwave measurements at cryogenic temperatures pose many challenges. For such measurements on superconducting circuits, PTB currently develops and pursues two strategies. First, electromech...
This talk describes recent research activities at the National Physical Laboratory (NPL) in cryogenic on-wafer S-parameter measurement. More specifically, the adaptation and improvement of a cryogenic...
This work proposes an innovative wearable energy harvesting system for wireless power transfer and energy harvesting. The system features a unique e-textile broadband dual-antenna array and a multi-ba...
This article addresses an innovative concept to enhance the security for IoT applications in the case of Simultaneous Wireless Information and Power Transfer. This is achieved by integrating a complem...
This paper presents a high-efficiency D-band rectifier for 6G energy harvesting applications. We introduce and verify a systematic design methodology for switching rectifiers, and then use it to reali...
The second harmonic produced by the nonlinearity of a diode rectifier can be utilised for backscattering communication. A rectifier for this purpose should not suppress the second harmonic, but its em...
