Low-cost integrated-circuit transmitter and receiver for UWB communications

Ultra-wideband (UWB) transmitter and receiver were developed for UWB communication systems. The developed transmitter and receiver are simple, compact and can be realized using planar or uniplanar integrated circuits. Measurement results of the transmitter show multiple monocycle pulses with duration from 0.4–1.2 ns, corresponding approximately to 0.2–3.9 GHz operating frequency range, and 6.5–9 V of peak-to-peak voltage. The developed receiver achieves a conversion loss of 4.5–7.5 dB (without baseband amplifier) and conversion gain from 6.5–9.5 dB (with amplifier) over a 5.5-GHz RF bandwidth, a dynamic range of more than 50 dB and low harmonic distortion in the baseband output signal.
