Structure of a frequency multiplier by 4 for WPAN networks applications

Abstract

This paper presents a chain of frequency multiplier by 4 based on 0.15 µm pHEMT from UMS foundry. This frequency multiplier will be used to generate carrier frequencies in the range of [56-64 GHz] in order to perform the RF signal demodulation of wireless communication link in the mm-wave band. The multiplier consists of a quadrupler stage followed by a two-pole highpass filter and a buffer amplifier. The multiplier chain can deliver 2.78 dBm of output power with 4 dBm input power. The signal at the fundamental frequency is rejected with a rate greater than 40 dB compared to the desired signal. Keywords-Mm-wave band, buffer amplifier, two pole high pass filter
