A novel transparent microwave absorber is proposed in this paper. Fluorine-doped tin oxide glass, glass and monolayer graphene are applied as the reflector layer, substrate and absorbing layer respectively to form a Salisbury absorber. The performance of the absorber is measured by the rectangular waveguide. An improved equivalent circuit model is proposed to analyze the transparent absorber. There is a good correlation between absorption coefficients obtained from the equivalent circuit model, 3-D full wave simulation and measurement. As high as 95% incident power can be absorbed by using the proposed absorber.

Water level is an important parameter for river hydrological monitoring. This paper introduces a compact K-band front-end with discrete components for river water level measurement. The radar front-end includes micro-strip antenna array, voltage-controlled oscillator and schottky diode mixer. To reduce the radar volume, only one micro-strip antenna array is used. To improve phase noise performance of the VCO, a compact mushroom ELV-EBG structure is used instead of conventional resonator. The results demonstrate that the antenna array has a gain of 23.8dB and three-decibel bandwidth in azimuth and elevation are both 11o; the output power of the voltage-controlled oscillator is more than 10dBm, and the phase noise is -95.6dBc/Hz@1MHz; the conversion loss of mixer is 7.18dB. The design satisfies the requirement of water level measurement radar applications.

A 24-GHz radar system for biomedical applications is designed, fabricated, and tested. The proposed radar system includes a flexible radio frequency (RF) board and a rigid baseband board. The RF board integrates two 4×4 patch arrays, a voltage controlled oscillator (VCO), two low noise amplifiers (LNA), and a six-port structure. The baseband board has baseband amplifiers as well as an on-board sawtooth voltage generator (SVG). The SVG generates a 155-Hz sawtooth voltage signal to control the VCO. A 450-MHz bandwidth frequency ramp with a center frequency around 24 GHz is transmitted. With the proposed radar system, the inverse synthetic aperture radar (ISAR) imaging method is used to track moving targets in a crowded environment with stationary clutter. The theory of ISAR imaging is detailed in this paper. Two experiments were carried out to reveal the capabilities of the radar system in tracking single and multiple moving targets. The radar system is featured as being flexible and portable. The complete radar system has overall dimensions of 118mm×45mm×15mm.

Two different approaches of capacitance-voltage (C-V) measurement were applied to the fabricated single-drift (SD) impact-ionization avalanche transit-time (IMPATT) structures. From both the C-V results, the carrier concentrations of depleted space-charge-region (SCR) width characteristics were calculated. According to the epitaxial thickness and the doping concentration of the lightly n-doped layer, the approach applied to a 30 × 2 μm2 IMPATT device, which is based on small-signal S-parameter characterization (0.04-40 GHz), showed better agreement compared with the approach applied to a C-V structure (0.64 mm2) using the conventional low frequency (1 MHz) C-V instrument. Additionally, the E-band IMPATT operation of the 30 × 2 μm2 device has been well modelled with the capacitance value extracted from the S-parameter based C-V measurement. The good agreement between device modelling and measurement within frequency range 0.04-110 GHz shows the reliability of the small-signal S-parameter device-level C-V measurement for real mm-wave application scenarios.

A wideband microstrip balanced-to-single-ended out-of-phase power divider (BTSEOOPPD) is proposed in this paper. Two types of two-stage cascaded BTSEOOPPD are studied, which both show wider bandwidth comparing with the single stage one. Two prototypes of the two types of two-stage BTSEOOPPD are analyzed, designed and compared, and type II shows wider isolation bandwidth than that of type I.

For the issue of deterioration in detection performance caused by dynamically changing environment in UWB MIMO radar, we propose a novel adaptive waveform design which is aimed to improve the ability of discriminating target and clutter from the radar scene. Firstly, we consider using a Dirichlet process mixture model (DPMM)-based clustering approach to discriminate individual extended targets. Then we apply the minimization mutual-information (MI) strategy between individual targets echoes to select the best waveform from an ensemble of UWB waveforms for transmission. With this approach, the radar system constantly learns about its surroundings and adopts its operational mode accordingly based upon the MI minimization criterion. Finally, simulation results demonstrate that the optimal design method brings an improvement in the target detection ability and target discrimination capability.

GaN technology has shown improved characteristics at high power and high frequency conditions, playing a key opportunity in the space industry. In this way, this paper presents a GaN-based MMIC power amplifier (PA), designed for X-band space applications. The PA design consists of a single stage class-B and achieves 10.5 dB gain at 9 GHz and an output power of 32 dBm. It is verified that the MMIC can operate also as a rectifier, with a conversion efficiency of around 40 % for a CW input signal of 28 dBm at 8 GHz. Additionally, two-tone measurements are performed and compared to the CW ones.

A wide locking range divide-by-4 injection-locked frequency divider (ILFD) using a standard 0.18 μm CMOS process is presented. The ILFD circuit is realized with a capacitive cross-coupled n-core MOS dual-resonance RLC-tank oscillator to extend the locking range. The core power consumption of the ILFD core is 11.872 mW. The divider's free-running frequency has dual-bands at 2.87 and 2.69 GHz by switching the varactor's control bias, and at the incident power of 0 dBm the locking range is 3.2 GHz (28.82%), from the incident frequency 9.5 to 12.7GHz.

A single-chip Optical Time Domain Reflectometer (OTDR) system-on-chip (SoC) for fiber-optic fault detection and localization is presented. The IC can be configured into several modes including high-performance mode (external modulator and expensive off-chip laser / APD), and low-cost mode (low power/gain and inexpensive laser / APD). Experimental optical measurements demonstrate that the maximum detectable fiber length of the proposed OTDR SoC can be as long as 25km, while the spatial resolution can achieve 2.5m, 4m and 10m, for various configurations. Compared with current discrete solutions on the market, the proposed OTDR system can reduce the cost by 100x, area by 5x, and power consumption by 4x.

This paper presents a low-power 11-bit 1-MS/s successive approximation register (SAR) analog-to-digital converter (ADC) that uses a self-dithering technique. The LSBs is employed as a dither to improve the resolution. Compared to converters that use the conventional dithering architecture, simulation results show that the proposed self-dithering technique improve the DNL performance with simplified hardware. The prototype is fabricated in 180nm 1P6M CMOS with MOM capacitor. At a 1.2-V supply and 1 MS/s, the post-layout simulation result shows an SNDR of 63.8 dB and consumes 40.3μW, and a figure of merit (FOM) of 32 fJ/conversion-step. The total area of the chip is 1 mm×1 mm.
