Ultra-wide bore 900 MHz high-resolution NMR at the National High Magnetic Field Laboratory.
Access to an ultra-wide bore (105 mm) 21.1 T magnet makes possible numerous advances in NMR spectroscopy and MR imaging, as well as novel applications. This magnet was developed, designed, manufactured and tested at the National High Magnetic Field Laboratory and on July 21, 2004 it was energized to 21.1 T. Commercial and unique homebuilt probes, along with a standard commercial NMR console hav...
متن کاملA 900-MHz CMOS Bandpass Amplifier for Wireless Receivers
This dissertation describes the design of a CMOS 900-MHz bandpass amplifier that is suitable for RF transceivers. The work employs the state-of-art inductive degeneration techniques to minimize the noise figure and explores the use of lossy spiral inductors in high frequency circuit to realize input matching networks on-chip. A Q-compensation circuit is included to achieve a 25-MHz 3-dB bandwid...
متن کاملPerformance of HSDPA and HSUPA at 900/2000 MHz bands
The main purpose of this paper is to study the High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) performance at 900/2000 MHz bands, considering a multiple users and services scenario. The intention is to evaluate the traffic management between the two carriers, the coverage and capacity aspects. A simulator was developed to study the multiple users’ scenario,...
متن کاملResonance Frequency Readout Circuit for a 900 MHz SAW Device
A monolithic resonance frequency readout circuit with high resolution and short measurement time is presented for a 900 MHz RF surface acoustic wave (SAW) sensor. The readout circuit is composed of a fractional-N phase-locked loop (PLL) as the stimulus source to the SAW device and a phase-based resonance frequency detecting circuit using successive approximation (SAR). A new resonance frequency...
متن کاملAn Amateur 900 MHz Spread-Spectrum Radio Design
System design principles and high-level design details are described for a new spreadspectrum radio design for the 900 MHz. Amateur band. The radio is designed to provide a 10-base-T interface as the data port, and is designed to provide transport of IP-based data. It is planned to provide both stand-alone and fully-networked hub configurations. The design is based on Frequency-Hopped Spread Sp...
