System-on-Package MHMIC Milimeter-Wave Frequency Synthesizer for 60 GHz WPANs

We present a low-cost millimeter-wave frequency synthesizer with ultralow phase noise, implemented using system-on-package (SoP) techniques for high-data-rate wireless personal area network (WPAN) systems operating in the unlicensed 60 GHz ISM band (57–64 GHz). The phase noise specification of the proposed frequency synthesizer is derived for a worst case scenario of an 802.11.3c system, which uses a 64-QAM 512-carrier-OFDM modulation, and a data rate of 5.775 Gbps. Our design approach adopts commercial-of-the-shelf (COTS) components integrated in a low-cost alumina-based miniature hybrid microwave integrated circuit (MHMIC) package. The proposed design approach reduces not only the system cost and time-to-market, but also enhances the system performance in comparison with system-on-chip (SoC) designs. The synthesizer has measured phase noise of -111.5 dBc/Hz at 1 MHz offset and integrated phase noise of 2.8° (simulated: 2.5°) measured at 57.6 GHz with output power of +1 dBm.

This work presents a two-stage 60 GHz Power Amplifier designed in a 65nm CMOS technology dedicated to low cost Wireless Personal Area Network (WPAN) applications. In order to provide a high efficiency operation, the PA is based on a Class E power stage. A Class F driver stage is also designed to provide a square waveform signal to the Class-E power stage. To realize the output networks of both driver and power stage at 60 GHz, distributed elements are used instead of lumped elements. The post-layout simulation results show a saturated output power of 15 dBm with a peak PAE of 26% at 60 GHz. It achieves a gain of 15dB at 60 GHz.

Nowadays, engineers are widely using accelerometers to record the vibration of structures for structural verification purposes. The main obstacle for using these data acquisition systems is their high cost, which limits its use to unique structures with a relatively high structural health monitoring budget. In this paper, a Cost Hyper-Efficient Arduino Product (CHEAP) has been developed to accurately measure structural accelerations. CHEAP is a system that is composed of five low-cost accelerometers that are connected to an Arduino microcontroller as their data acquisition system. Test results show that CHEAP not only has a significantly lower price (14 times cheaper in the worst-case scenario) compared with other systems used for comparison but also shows better accuracy on low frequencies for low acceleration amplitudes. Moreover, the final output results of Fast Fourier Transformation (FFT) assessments showed a better observable resolution for CHEAP than the studied control systems.

This paper provides details concerning the design of an integrated voice and data communications link for a Local Area Network that must utilize residential type 2 pair telephone wiring as its transmission medium. The communications link can provide a worst case total data rate of 80 K bps (full duplex), 80 K analog samples of audio signals total (full duplex), as well as power and ground for remote terminals. In a system design that utilizes the communications link discussed here, the above total values of data and audio information flow can be divided by the number of terminals anticipated in the system in any ratio desired. The intent of the design of the communications link is to provide what is believed to be the most cost effective means of implementing an intelligent network of consumer based products in a residential or small business type of environment. In this document, the original technical problem is discussed along with details concerning the development of the solution presented here. The system design example that is presented is only provided as an aid to understanding how the communications link can be applied and is not the focus of the central concept. In that example, the system is comprised of 8 remote terminals and one central control terminal — all of which are voice and data devices. Therefore, the available continuous data rate per terminal is 10 K bps with 5 Khz full duplex audio.

Gnss Data

The so-called Real Time Kinematic (RTK) option, which allows one to determine with cm-level accuracy the Unmanned Aerial Vehicles (UAV) camera position at shooting time, is also being made available on medium- or low-cost drones. It can be foreseen that a sizeable amount of UAV surveys will be soon performed (almost) without Ground Control Points (GCP). However, obstacles to Global Navigation Satellite Systems (GNSS) signal at the optimal flight altitude might prevent accurate retrieval of camera station positions, e.g., in narrow gorges. In such cases, the master block can be georeferenced by tying it to an (auxiliary) block flown at higher altitude, where the GNSS signal is not impeded. To prove the point in a worst case scenario, but under controlled conditions, an experiment was devised. A single strip about 700 m long, surveyed by a multi-copter at 30 m relative flight height, was referenced with cm-level accuracy by joint adjustment with a block flown at 100 m relative flight height, acquired by a fixed-wing UAV provided with RTK option. The joint block orientation was repeated with or without GCP and with pre-calibrated or self-calibrated camera parameters. Accuracy on ground was assessed on a fair number of Check Points (CP). The results show that, even without GCP, the precision is effectively transferred from the auxiliary block projection centres to the object point horizontal coordinates and, with a pre-calibrated camera, also to the elevations.
