Sir,
Then can i say Fmax is the major parameter ?I got a quotation of two foundries one is having Ft= 60GHz and other is Ft=90GHz, which one shall i choose ?Any other parameter can also i have to consider ?
My frequency of operation is 12-18GHz, Can i use HBT instead of PHEMT?
In some of the readily available products i have seen gain amplifiers of single supply and the manufacturer is telling the device used in design is enhancement mode type instead of depletion mode , where gate and drain has to bias sequentially..
how to comapare enhancement mode device over depletion mode device !
Thank you.
