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).
