Abstract :
The stringent emission mask and interference specifications in ultra-wideband (UWB) impulse radios present great challenges for the transceiver architecture design and circuit implementation. This paper proposes to use integrated distributed transversal filters (DTF) for pulse shaping in the transmitter and for narrow-band interference (NBI) suppression in the receiver. Analyses show that an integrated DTF can accurately generate notches at multiple frequencies with tunability and relatively low power consumption. A 7-tap DTF prototype was implemented using a commercial 0.18 mum SiGe BiCMOS technology. Measurement results demonstrate the pulse shaping and interference suppression capabilities of DTFs. The typical power consumption of the prototype is 30 mW
