This paper presents a new cross-shaped TM010 dual-mode dielectric resonator which provides 28.8% and 78% volume reduction in comparison with two single-mode TM and one dual-mode TE dielectric resonator, respectively. Based on a design method which is improved to avoid the tuning efforts, three filters are designed. A comparison between simulation and measurement results verifies practically the concept of dual-mode operation and its application for filter design.

In this paper, a new technique is presented for the analysis of the transient dynamics of microwave oscillators. The technique makes use of a nonlinear admittance function that can be identified in commercial Harmonic Balance software. This function is included in a time-frequency domain equation governing the transient dynamics. The equation provides the growth rate function of the first harmonic amplitude, which allows an exhaustive analysis of the transient speed from the neighborhood of the dc solution to the oscillation establishment, with no need for a numerical integration, as in time domain or envelope-transient methods. The technique has been applied to predict the length of the transient towards the oscillating state of a FET oscillator at 5 GHz.

A room temperature LNA suitable for Square Kilometer Array band 1 (0.35-1.05 GHz) has been designed, fabricated and tested. The design is based on InP HEMTs, and focused on minimizing losses in the input matching network. Noise measurement methods in two different labs were used to confirm the 10 K noise temperature of the LNA. The gain was flat at 50 dB and the input and output return loss better than 10 dB in most of the band.

We provide a technique to generate and characterize a precision wideband millimeter-wave linear chirp signal. This linear chirp signal has 2 GHz of bandwidth, a center frequency of 30 GHz and repeats every 50ns. The signal can be used as a reference waveform for characterizing the phase dispersion in wideband receivers. The generation of the signal is based on frequency multiplication of a linear chirp signal that is generated by an arbitrary waveform generator (AWG). The signal is characterized by an equivalent time sampling oscilloscope that is synchronized to the 12 GHz sampling clock of the AWG. The oscilloscope measurements are corrected for timing jitter, mismatch and impulse response.

This paper presents a diversity integrated circuit (IC) for digital satellite radio (SDARS) at 2.3GHz. The IC contains an RF circuit which enables fast adaptive processing of up to three antenna signals for maximum ratio combining in a fast fading scenario. The RF front-end of the diversity system is integrated using 150nm CMOS technology. The phase of each of the three input paths can be adjusted in quantized steps of 45° from 0° to 360°. If the input signal of one path suffers from fading, a single path can be completely turned off for reducing the power consumption. The diversity IC is evaluated by means of laboratory measurements as well as by tests where antenna signals of real fading scenarios are processed using the presented IC. The results show a typical improvement in radio reception of more than a factor of 4 compared to a conventional reception system.

In conventional passive radio frequency identification (RFID) systems, downlink (reader to tag) and uplink (tag to reader) overlap on the same carrier frequency, which leads to severe self-jamming and reader collision problems. To resolve these issues, nonlinearity in passive RFID tags can be exploited to generate second or higher order harmonics for uplink data communication. The design of harmonic tag that allows efficient energy harvesting and harmonic generation at the same time is critical. We present Harmonic-WISP, the first harmonic RFID system integrated with the open-source wireless identification and sensing platform (WISP). Harmonic-WISP adopts a new routing strategy to ensure full power utilization in both energy harvesting and harmonic generation modes. The new platform can fundamentally eliminate self-jamming issues and can greatly reduce reader-to-reader interference. By integrating with WISP, the proposed platform can further allow flexible implementation and evaluation of efficient multiplexing and security protocols.

Backscatter radio is being increasingly used for identification, sensing, and localization. The increased number of pervasive IoT systems that utilize backscatter radio as a low-power and low-cost communication scheme has led to dense deployments of tags that need to operate under bandwidth constraints. However, typical backscatter radio modulators perform switching “on-off” operation and modulate data with rectangular pulses, which are known to occupy an extensively wide bandwidth. This work derives new techniques and demonstrates front-ends that control the tag reflection coefficient over time in a continuous manner, thus enabling the generation of arbitrary backscattered waveforms and reduced bandwidth occupancy. The principles presented hereby will enable sophisticated tags to perform more complex modulation schemes, while maintaining the RF front-end complexity at low levels, using a single PIN diode or FET.

This paper presents a fractional 88-105 GHz frequency synthesizer module developed to support THz spectrometer instruments for planetary exploration. The presented module features low power operation and a small form factor to be compatible with the demanding payload requirements of NASA planetary missions. The core of the module is a CMOS System-on-Chip (SoC) containing a 50 GHz phase-lock loop and W-band frequency doubler, driven by a direct digital frequency synthesizer (DDFS) and DAC to provide finely tuned reference frequencies allowing fractional operation. The chip contains a wide range of calibration functions for temperature and radiation exposure compensation. The demonstrated module draws a total of 152 mW of power from a USB connection and provides coverage from 88-105 GHz with output powers up to -15 dBm. The offered mid-band phase noise is measured at 89.5 dBc/Hz evaluated at 1 MHz offset from the carrier.

Next generation radio telescopes will have a very large number of antenna elements. For such systems, ultra-low-noise ambient-temperature integrated CMOS receivers can address some design challenges, such as size, weight, power consumption, and cost. This paper describes the development of one such receiver. Developed in 65-nm TSMC CMOS, it operates between 0.7 and 1.5 GHz and achieves minimum noise temperatures of 16 K at 1.5GHz and power gain of 70 dB, while consuming 265 mW of power.

A new topology of a reflection amplifier is proposed and demonstrated using a CMOS FD-SOI 28 nm process for high gain reflectarray antenna applications. The design is based on two sets of cross coupled pairs which are coupled inductively. An internal oscillations-block was implemented in order to improve the stability of the amplifier. Variable stable gain of 5-25 dB at the bandwidth of 106-127 GHz was achieved, with output power of up to 0 dBm (measurement limited). The total power consumption was 6-20 mW, depending on the exact bias configuration. The reflection amplifier results with a 3-dB bandwidth of up to 18%. The design consumes a core area of only 90×80 μm2 and allows the implementation of high efficiency active reflectarray antennas.
