JUPITER

CDMA and FM (AMPS) I/Q Filter

Preliminary Information

DS4724 - 3.1 May 1998

The JUPITER circuit is designed for use in dual band and dual

mode mobile phones (CDMA/AMPS) and meets the requirements

for IS-95 when used with other chips from Mitel that form the

Planet chipset. JUPITER is an active filter incorporating circuits

for receiving both CDMA and FM (AMPS).
