Objectives

The main objective of the project is to provide a distribution module aimed for protecting power buses devoted for powering RF amplifiers elements within an active antenna. A latching current limiter (LCL) is implemented between main power buses and the active element. Thanks to the use of GaN technology and digital control, a switching LCL can be developed providing unpreceded performances in terms of voltage drop, reaction time, limitation levels and parameters programmability like current limitation and tripoff levels.

Challenges

Main challenges of the project are:

To provide low voltage drop Latching Current Limiters (LCL)
To reduce LCL output impedance
To allow flexibility in the LCL parameters (limitation current and trip-off time)
To increase the number of LCLs per module in order to increase the distribution density

Benefits

IDEAA provides the means to increase by a factor of two the distribution density, i.e. number of distribution elements in a certain amount of volume.

It provides unpreceded flexibility in the protection parameters, allowing to change trip-off time and current limitation on the fly.

Last, but not least, IDEAA provide very low output impedance in a wide range of frequencies to provide high power buses quality.

Features

Programmable current limitation
Programmable Trip-off time
Low output impedance

Plan

The project is divided in 3 phases:

Phase I. Concept / Architecture. Up to RR.
Phase II. Design. Up to PDR.
Phase III. EM MAIT. Starts with EM MRR and finish with EM DRB

Current status

The current status is that PDR has been successfully passed and Design of board and PCB are ongoing, after that purchase will start and EM MRR will be done.
