A 60 GHz HEMT-MMIC analog frequency divider by two
Monolithic technologies on GaAs allow us to build complex non-linear circuits at very high frequencies. However accurate predictions of circuit performances can be obtained only if non-linear CAD tools are available. A new method has been proposed allowing to overcome the difficulties encountered with commercial CAD software packages when we want to simulate synchronized circuits. For the first time a 60/30 GHz MMIC analog frequency divider has been designed and processed with a 0.25/spl mu/m HEMT process at the THOMSON-CSF foundry. The results obtained are very close to the predicted performances and allow us to think that broadband analog frequency dividers may now be designed at higher frequencies.
