[Introduction] When a radio frequency (RF) coil is designed and built for MR imaging, its performance is judged on the basis of achieving uniform imaging B1field and high signal-to-noise ratio (SNR). However, there is an intrinsic trade-off between B1-field uniformity and high SNR in the configuration of RF coil; a large RF coil tends to generate a more uniform B1-field but lower SNR, because i...

This article introduces a power-efficient and low-cost CMOS 28-GHz phased-array beamformer supporting fifth-generation (5G) dual-polarized multiple-in-multiple-out (MIMO) (DP-MIMO) operation. To improve the cross-polarization (cross-pol.) isolation degraded by antennas propagation, analog-assisted cross-pol. leakage cancellation technique is implemented. After high-accuracy cancellation, more t...

anomaly detection (ad) has recently become an important application of hyperspectral images analysis. the goal of these algorithms is to find the objects in the image scene which are anomalous in comparison to their surrounding background. one way to improve the performance and runtime of these algorithms is to use dimensionality reduction (dr) techniques. this paper evaluates the effect of thr...

In this study, the design of a dual-band mode converter, which provides transition from rectangular waveguide T E10 to circular TM01 and operates simultaneously in telemetry/telecommand (TT&C) frequencies, is presented along with its equivalent circuit level measurement technique. This converter designed uniformly excite TT&C slot antennas used satellite communication symmetric mode. The struct...

We propose and demonstrate a cost-effective half- duplex transceiver for Fiber-to-the-Room (FTTR) network by using homemade uncooled isolator-free distributed feedback (DFB) laser as both receiver (Rx) transmitter (Tx). AlGaInAs multiple quantum wells (MQWs) partially corrugated grating are utilized operation of the DFB lasers. Tx/Rx mode switching is implemented specially designed complementar...

In this work, a low cost Bluetooth Low Energy (BLE) transceiver for wireless sensor network (WSN) applications, with a receiver (RX)-matching network-reusing power amplifier (PA) load inductor, is presented. In order to decrease the die area, only two inductors were used in this work. Besides the one used in the voltage control oscillator (VCO), the PA load inductor was reused as the RX impedan...

Space-time codes were designed for fading environments in order to improve system capacity and/or to achieve a diversity gain. In this paper, a novel possible application of the Alamouti space-time block code (STBC) for two transmit antennas is investigated, to provide a switchless alternative in current resilient microwave radio links. Resilient means that transmitter (Tx) and receiver (Rx) ar...

In this article, a $Ka$ -band satellite communication (SATCOM) transceiver is first presented using standard CMOS technology. The proposed SATCOM consists of high-linearity transmitter (TX) and dual-channel receiver (RX); both TX RX a...

This article introduces a four-element 300-GHz-band bi-directional phased-array transceiver (TRX). The TRX utilizes the same antenna, signal path, and local oscillator (LO) circuitry to operate either in transmitter (TX) mode or receiver (RX) mode. TX adopts outphasing technique increase average output power for higher order modulation schemes by utilizing two mixers that are connected directly...
