A 6–18 GHz GaAs multifunctional chip for transmit/receive modules

In this contribution the development, design, fabrication and test of a highly integrated broadband multifunctional chip is presented. The MMIC covers the C-, X- and Ku-Band and it is suitable for applications in high performance Transmit/Receive Modules. In less than 26 mm
²
, the MMIC embeds several T/R switches, low noise/medium power amplifiers, a stepped phase shifter and analog/digital attenuators in order to perform the RF signal routing and phase/amplitude conditioning. Besides, an embedded serial-to-parallel converter drives the phase shifter and the digital attenuator leading to a reduction in complexity of the digital control interface.
