A 0.5-30 GHz monolithic PHEMT amplifier for ESM systems applications

摘要

ESM wide open receivers have need, next to antenna, to a wide bandwidth preamplifier with a low noise figure, in order to increase the sensitivity. It is also important to have a high output third order interception point to reduce the harmonics and spurious. For this reason a low noise MMIC GaAsFET Pseudomorphic HEMT amplifier has been designed and developed in collaboration with Alenia Ricerche Foundry. Based on a travelling-wave amplifier structure, this component has good performances in term of noise figure, bandwidth, return loss and output power.
