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).
FEATURES
s Low Power and Low Voltage Operation with a
Sleep Mode
s Integrated CDMA and FM Filter with Wide
Dynamic Range
s Low Inband Gain Ripple Performance and Good
I/Q Matching for the Filter

ESD PROTECTION
All pins are protected against electrostatic discharge to both
supplies. At least 2kV protection is provided to MIL-STD-883D
Method 3015.7 (human body model).
