In this work, a compact 220 GHz polarimetric LNA front-end is reported. The front-end is intended to be integrated into a polarimetric direct detection receiver for sensing of temperature and humidity profiles in the Earth’s atmosphere. We show measured channel gain of approximately 35 dB per channel, with a corresponding noise figure of 3.9 dB. This work represents the first 220 GHz polarimetric direct detection front-end, and is enabled by an advanced 25 nm InP HEMT MMIC technology.

The ongoing technical need for miniaturisation and the increasing number of wireless standards and frequency bands implemented in modern radio-frequency (RF) transceiver systems drive the need for highly integrated circuit technologies with high performance. Especially low-phase noise oscillators, which are required at nearly all frequencies in multi-band RF modules, often consist of components using different technologies, e.g., micro-electromechanical systems (MEMS) resonators and microelectronic circuits, usually with one resonator per output frequency. This paper presents the compact implementation of a multi-frequency MEMS oscillator on a silicon-ceramic composite substrate, tailored to the construction of multi-physical RF modules. MEMS devices and microelectronic circuits are fabricated and assembled on opposite sides of the same substrate, in order to nearly halve the substrate area used. The benefits of integrated circuits for switching, frequency doubling, and dividing increase the scope of functions by keeping the module size nearly constant. This results in a highly integrated oscillator module with optimised phase-noise performance.

The design and characterization of a low noise amplifier optimized for the readout of microwave kinetic inductance detectors is described. The work is first motivated through a description of microwave kinetic inductance detectors and a discussion of the requirements for the low-noise amplifiers employed for readout of these devices. Next, the design of a two-stage silicon germanium cryogenic integrated circuit low noise amplifier is presented. The small-signal and large-signal characteristics of the fabricated amplifier are then measured. It is shown that, at a physical temperature of 16 K, the amplifier achieves a gain of greater than 30 dB and an average noise temperature of 3.3 K over the 0.4–1.2 GHz frequency band while dissipating less than 7 mW. Moreover, the wideband compression characteristics are measured it is found that the linearity of the amplifier is sufficient to support frequency domain multiplexed readout of more than 500 detectors.

In this paper an algorithm for accurate distance estimation using a frequency modulated continuous wave (FMCW) radar is presented. First, a phase calibration of the radio and intermediate frequency path transfer function compensates for distance dependent effects. The unambiguous frequency of the target is used for range cell estimation and the ambiguous but highly accurate and precise target phase is combined with this range cell information.To demonstrate the capabilities of the proposed signal processing chain, distance measurements using an 80 GHz wideband FMCW radar sensor with a movable target and a maximum measurement range of up to 5 m have been carried out. The target is mounted on a precision linear track and the position is laser interferometer referenced. For free space measurements with a target in about 1.2 to 5 m distance, the unambiguous single measurement accuracy has been improved from about ±400 µm to ±8 µm. A potential application of a radar system using this algorithm is the online measurement of machine tools.

This paper reports on the RF design of multi-band bandpass filters (BPFs) along with a simple tuning method to obtain multiple levels of transfer-function reconfigurability. The proposed multi-band BPF concept is based on multi-resonant cells that are incorporated within the two transversal paths of a doublet. It is shown that by solely reconfiguring the resonant frequencies of its constituent resonators, multiple quasi-elliptic-type passbands can be created and controlled in terms of: i) center frequency, ii) bandwidth, and iii) number through their intrinsic RF switching and/or merging. In addition, the proposed filter concept allows for the realization of i) an all-reject state and ii) a single-band BPF state with >5.1:1 BW tuning. The theoretical design principles of the multi-band BPF approach are presented by means of coupling routing diagrams and synthesized examples. For proof-of-concept demonstration purposes, a tri-band BPF microstrip prototype was designed, manufactured, and measured.

We propose an approach for characterizing the complex frequency response of sampling oscilloscopes using a calibrated large-signal network analyzer (LSNA) and a broadband pulse source. First, we perform a full wave-parameter calibration of the LSNA using its internal continuous wave (CW) sources. Then, we replace the internal CW sources with an external broadband pulse source and measure it with the calibrated LSNA and oscilloscope connected to the LSNA test port. The complex frequency response of the oscilloscope’s sampler is derived in the frequency domain as the ratio of the oscilloscope signal spectrum to the calibrated LSNA signal spectrum. We achieve less than 0.7 dB amplitude and 5 degrees phase difference up to 45 GHz between the proposed LSNA calibration and previous NIST electro-optic sampling (EOS) characterization of the same sampler.

A quasi-uniform transversely slotted substrate integrated waveguide (SIW) leaky-wave structure with enhanced beam-scanning rate has been proposed and studied in this paper for millimeter-wave applications. By adopting a long inductive transverse slot in each unit cell while keeping a small period length, the sensitivity of effective phase constant (i.e. the slope of effective phase constant versus frequency) of the unit cell can be increased significantly, thereby resulting in a quasi-uniform leaky-wave antenna with a fast beam-scanning property. The working principle is elaborated with an equivalent circuit model of the unit cell, and both of circuit-based and full-wave simulations are conducted to verify the design concept. To do the demonstration, a limited frequency band from 34 to 36 GHz (5.7%) has been designated specifically to implement the proposed leaky-wave antenna. Furthermore, a taper design with -25 dB Taylor distribution is carried out for the antenna to achieve a low sidelobe radiation. A prototype is then fabricated and tested. Experimental results show that the beam can be scanned from 17o to 58o with low sidelobe levels over such a narrow bandwidth. The simulated and measured results are in a good agreement.

We explore large-signal network analysis for the over-the-air test of up-converting and down-converting phased arrays. The approach first uses a vector network analyzer to characterize a three-dimensional test environment at RF. The vector network analyzer is then power- and phase-calibrated for the characterization of up-converting and down-converting phased arrays with an IF input or output. We illustrate the approach with measurements of a down-converting phased array.

We present a monolithically fabricated PolyStrata®based 64x64 array composed of 4096 tightly coupled dipole Dband elements connected by a 4096-way reactive corporate feed network, operating over the 130-175 GHz frequency range. Measured farfield patterns, return loss and realized gain versus simulation are captured. Additionally, we demonstrate the repeatability of the fabrication process by reporting on the performance of multiple smaller 16x16 arrays fabricated on the same mask set. Monolithically fabricated PolyStrata®-based radiators can be an enabler for wafer-level scale arrays which require stable and well-matched input impedance, high efficiency and broadband performance.
