Fostering New Trends In MMIC Design



Aelius Semiconductors' team of MMIC design engineers carries a combined 70+ man years of dedicated MMIC design experience. Each engineer works with industry standard MMIC CAD software that includes circuit simulators like Agilent ADS, AWR Microwave Office along with ADS momentum, MWO Axiem and Sonnet for EM simulation. In addition, they have access to other higher end software for 3D EM simulation. The former Microelectronic Technologies Division of AMPL which grew to be India's largest and best equipped GaAs MMIC design and production house, has been spun off to Aelius Semiconductors Pte Ltd, Singapore.

Aelius has a fully equipped state-of-the-art assembly, test and packaging facility which includes its own RF on-wafer probing test and measurement facility for optimizing designs to various foundry processes. On-wafer RF probing provides an excellent platform to validate and fine tune designs.

This division has access to the largest Space Qualified MMIC assembly and test facility in India. Packaging of MMICs is also undertaken as per customer requirement. Using the in-house facility, Ceramic and hermetically sealed packaged MMICs can be delivered. For Hermetically sealed packages, gross and fine leak test can be conducted as required. Our Environmental test facility is capable of carrying out MIL grade, Jedec as well as IEC compliant qualification tests including Temperature-cycling, Burn-in, Mechanical Shock test, vibration test on all three axes, and thermo-vacuum tests.
