Multiresonant Chipless RFID Tag for Directional Strain Measurement
A RFID sensor tag for real-time health monitoring of the magnitude and direction of metal surface strain is demonstrated. The presented experimental data shows that the average sensitivity of the resonators is -4.94 and 1.14 kHz/με in the electric length and width directions, respectively.

Load-Modulating Loop Combiner for Linear Power Amplification
This work presents a PA architecture employing a feedforward-like loop structure for the linearization of a load-modulated PA. A hardware demonstrator operating at 3.5 GHz with 42-dBm peak output power and 55% PDE in CW is shown.
MMIC X3 Multiplier Die Delivers 20 to 45 GHz Output
Mini-Circuits’ new CY3-453-D+ MMIC X3 Multiplier die converts input signals from 6.66 to 15 GHz into output signals from 20 to 45 GHz. With an input power range from +12 to +17 dBm, it’s an excellent candidate for frequency conversion in 5G backhaul systems, Satcom, radar and more.

Wideband Surface Acoustic Wave Filter at 3.7 GHz With Spurious Mode Mitigation
This paper presents a new surface acoustic wave (SAW) filter using a 32° Y-X LiNbO3/SiO2/Si heterostructure with a high electromechanical coupling coefficient of 23%. A SAW filter is demonstrated with a large bandwidth of 730 MHz (FBW of 19.5%) at 3.74 GHz, a low insertion loss of 3.03 dB, and a flat passband.

W-Band Graded-Channel GaN HEMTs With Record 45% PAE at 94 GHz
This article presents the W-band large-signal power and efficiency performance of Ga-polar graded-channel AlGaN/GaN HEMTs with a 50-nm gate-length mini-field-plate T-gate. The pre-matched GC GaN HEMT devices with on-chip pre-matching networks show a measured peak PAE of 45% at 94 GHz at 2.1 W/mm associated power density.
