Chip on Board 3–10-GHz Impulse Radio Ultra Wideband Transmitter With Optimized Die to Antenna Wire Bond Transition

Abstract

In this paper, a low power and low cost ultra wideband impulse radio transmitter is presented. The transmitter includes a pulse generator integrated in a 0.13- $\mu{\rm m}$ standard CMOS technology and an antenna printed on the chip carrier. The board is manufactured with Roger 4003 laminate substrate and has a total area of 50 mm $\times\,$ 18 mm. The transmitter provides 1.4 V peak to peak Federal Communications Commission compliant pulses at antenna input for data rates up to 36 Mb/s in an on–off keying modulation scheme. The transmitter's power consumption is 12 mW at 1.2-GHz pulse repetition frequency and the energy consumption is 10 pJ per pulse. A 365-mV peak voltage emitted pulse is measured in an anechoic room at 0.8 m range with a receiver, including a horn antenna (8.3 dBi), a LNA (32 dB), and a 12-GHz real time oscilloscope.
