RF Transceiver with Antenna Design for Ultra-wide Band Applications

Abstract

The proposed article introduces RF wireless integrated transceiver for ulra-wideband wireless applications. The proposed wireless integrated transmitter consists of two-stage power amplifier (PA) with pre-distorter, band-pass Gm-C filter, distributed single-pole double-throw (SPDT) radio frequency (RF) switching, low noise amplifier (LNA) with balun and antenna design. The presented PA design presents conversion gain of 12.8 dB, the output 1-dB compression point (OP 1dB) of-1.3 dBm and power added efficiency (PAE) higher than 3.04%, respectively. The presented LNA presents return loss of input higher than 10.32 dB, return loss of output higher than 10.77 dB, the exhibits gain from 8.16 to 13.1 dB, isolation higher than 42 dB, the exhibits noise figure from 4.48 to 7.66 dB, the exhibits input 1-dB compression point (IP 1dB) from-13.43 to-5.43 dB, respectively. The implemented integrated transmitter using 0.18um CMOS technology has experimental outdoor/indoor throughput base on channels, distance and concurrently complies with the Bluetooth wireless requirement.
