CONCLUSION
GSM/DCS1800 solution for dual band radios or dual band car
antenna amplifiers with standard products such as
MRFIC0917/MRFIC1817/MC33169/MMSF4N01HD at 3.6 V
and MRFIC0913/MRFIC1818/MC33169/MMSF4N01HD at
4.8 V. Reusing these standard products leads to cycle–time
reduction, ease–of–use and time–to–market advantages.
