摘要

介绍了一种用于脉冲无线电超宽带无线通信系统的双通道定时阵列发射机。发射机可以在两个独立的发射路径上产生超宽带脉冲，路径延迟差可调0~250ps，以实现波束形成能力。通过注入锁定，输入基准为800MHz，产生的超宽带脉冲以4GHz为中心，覆盖3~5GHz频段，旁瓣抑制10db。该发射器采用0.18μm CMOS技术制造，在1.8V电源下，功耗为37mA，功率为10Mbps。

3–5GHz IR-UWB timed array transmitter in 0.18μm CMOS

This paper presents a dual-channel timed array transmitter for impulse radio ultra wide band wireless communication system. The transmitter can generate UWB pulses in two separate transmitter paths with tunable path delay difference of 0~250ps to achieve beamforming capability. Through injection locking with 800MHz input reference, the generated UWB pulse centers at 4GHz and covers 3~5GHz band with 10-dB side-lobe rejection. Fabricated in 0.18μm CMOS technology, the transmitter consumes 37mA at 10Mbps under 1.8V supply.
