Abstract :
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 mm2, 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.
