An experimental Unmanned Aerial Vehicle (UAV) Synthetic Aperture Radar (SAR) Sensor has been designed and developed at Multimedia University, Malaysia. This airborne system is an inexpensive C-band, single polarisation, linear FM airborne radar sensor. The system will be used for monitoring and management of earth resources such as paddy fields, oil palm plantation and soil surface. A series of...

The ever growing volume of backplane communications pushes the data rate toward 20Gb/s for the next-generation transceivers. Over the years, chip designers have been seeking different data formats to overcome the loss of electrical channels. Among the existing solutions, duobinary signaling manifests itself in bandwidth efficiency as (1) its spectrum occupies only half as wide as that of NRZ da...

This paper presents a radio-frequency (RF) transceiver designed, using a standard 0.18 μm CMOS process, for operation in the 2.4 GHz ISM band. The receiver has a sensivity of -64 dBm and consumes 3.5 mW from a 1.5 V supply. The RF transmitter delivers an output power of +11 dBm (15 mW) with a power consumption of 45 mW. These features make the RF transceiver suitable to be integrated in microsy...

Efforts towards commercializing higher-speed optical transmission have demonstrated the need for advanced modulation formats, several of which require similar transceiver hardware architecture. Adaptive transceivers can be built to have a number of possible operational configurations selected by software. Such software-defined transceiver configurations can create specific modulation formats to...

This paper describes an optimization tool-based design strategy for a Current Mode Logic CML divide-by-2 circuit. Representing a building block for output frequency generation in a RFID protocol based-frequency synthesizer, the circuit was designed to minimize the power consumption for driving of multiple loads with unbalancing (at transceiver level). Implemented with XFAB XC08 180 nm technolog...

A high-efficiency class-E power amplifier is proposed for digital PWM microwave signal amplification in the improved Kahn Technique transceiver. The benefit of using a class-E power amplifier in this design approach is to improve efficiency of the power amplifier due to its switching mode operation, theoretically 100 % with ideal conditions. In this paper a class-E amplifier is designed for the...

In this paper, we propose a structure of an array transceiver for W-CDMA base station based on cdma2000-1x RTT. The structure has several advantages such as practical SINR (Signal to Interference plus Noise power Ratio) measure, efficient channel estimation, and array transceiver based on LMS/DA (LMS with decision-aid) in cdma2000-1x system. Under this structure, BER (Bit Error Rate) improvemen...

We critically evaluated analog and digital transceivers for magnetic resonance (MR) imaging systems under identical experimental conditions to identify and compare their advantages and disadvantages. MR imaging experiments were performed using a 4.74-tesla vertical-bore superconducting magnet and a high sensitivity gradient coil probe. We acquired 3-dimensional spin echo images of a kumquat wit...

analogdialogue.com The AD9361 and AD9371 RadioVerseTM wideband transceiver families both offer an unparalleled level of integration, as well as a plethora of features and many user-selectable options. The two families have significantly different levels of performance in several key areas and power consumption is also quite different between the two product families. Image rejection is one of t...
