MMIC Chipset for wideband multifunction T/R Module

This paper reports on the design, fabrication and test of key MMIC components developed for wideband Transmit/Receive Module applications in the framework of a bilateral Research Programme at System level between Italy and Sweden MoDs (M-AESA) with Technological Studies performed in order to guarantee the feasibility of main hardware critical aspects. The Chipset comprises a multi-function phase-amplitude control chip (“core-chip”) and two wideband HPA MMICs. In the 2-18GHz bandwidth the True Time Delay (TTD) core-chip enables a time delay up to 124ps with a LSB of 4ps and an unwrapped phase deviation from linear behaviour of ± 7deg. The two-octave bandwidth HPA operates in the 4.5-18GHz in CW and provides an output power of 33±1dBm. The other wideband HPA is focused on C and X band radar frequencies (5-12GHz) and operates in pulsed mode with an output power of 36±1dBm.
