UWB Radio Module Design for Wireless Intelligent Systems-From Specification to Implementation

In this paper, we designed an impulse-based ultra wideband (UWB) radio module (low band) for wireless intelligent system applications such as radio frequency identification (RFID) and wireless sensor networks (WSN). The UWB radio module includes transceiver block, baseband process unit and power management block. The transceiver circuits include Gaussian pulse generator, wideband low noise amplifier (LNA), multiplier, integrator and timing circuits, which use 0.18mum, 1P6M CMOS technology. The wideband LNA has a power gain of 10dB and minimum noise figure of 2.7dB. For UWB transceiver, the power consumption of transmitter is lower than 1mW while the receiver is about 23mW. The liquid-crystal-polymer (LCP)-based system-on-package (SoP) technology is used to implement the UWB radio module for low power, low cost and small size
