TLDR
In this article, two UWB multiband systems, frequency hopping and Spectral Keying, have been described, both of which meet the stringent requirements provided by IEEE 802.15.3a.Abstract:
The recent FCC frequency allocation for UWB has generated a lot of interest in UWB technologies. There is 7,500 MHz of spectrum for unlicensed use. The main limitations are provided by the low-power spectral density and by the fact that the transmit signal must occupy at least 500 MHz at whole times. IEEE 802.15.3a is being developed for high-bit-rate PAN applications, and UWB is the most promising technology to support the stringent requirements: 110, 200, and 480 Mb/s. Two UWB multiband systems, frequency hopping and Spectral Keying, have been described in this article. Both systems meet the stringent requirements provided by IEEE 802.15.read more

Frequency Triplexer for Ultra-Wideband Systems (6–9 GHz)
TL;DR: A triplexer for ultra-wideband radio implemented entirely with distributed microstrips is presented and a good agreement between simulation and measurement was obtained, e.g., less than 0.3 dB difference in the forward transmission in the majority of the frequency band.

A Discrete-Time Digital-IF Interference-Robust Ultrawideband Pulse Radio Transceiver Architecture
TL;DR: Several signal-processing techniques to eliminate sampling images in the transmitter as well as spurious image responses in the receiver are presented and the proposed architecture is digitally intensive and, hence, can take advantage of technology scaling.
