Abstract

This paper proposes a wideband linearisation
technique for third-order intercept point (IP3) improvement in
low noise amplifiers (LNAs). The proposed LNA is designed
for mid-band 5G (3-4GHz) wireless receivers and it is based
on a cascode topology. An auxiliary transistor provides a
feedforward correction path for third-order intermodulation
(IM3) cancellation. The effects of the second harmonic on the IM3
are also considered in the modelling. Theoretical and simulation
analysis of the circuit result in a DC power consumption of
306mW from a supply voltage of 3V, an OIP3 of 30.8dBm, noise
figure (NF) of 0.94dB and 13.8dB of power gain are obtained.
The LNA is simulated for a hybrid circuit implementation using
a 400um GaAs packaged transistor.
