CM1300  
4 Channel EMI Filter Network  
Product Description  
Features  
Functionally and pin compatible with CSPRC032A  
The CM1300 is a 4-channel low pass EMI filter (R-C-R  
configuration) manufactured in a Chip Scale Package  
(CSP). Many portable applications require the attenua-  
tion of signals in the 800-3000 MHz band. California  
Micro Devices’ unique thin film technology provides a  
minimum of –25dB of attenuation over this frequency  
band.  
OptiGuardTM coated for improved reliability at  
assembly  
4 EMI filter lines per device  
Filters attenuate to –30dB at 3GHz  
CSP package minimizes cross-talk  
9-bump 2.485mm X 0.985mm Chip Scale  
Package (CSP), 0.5mm pitch  
0.30mm Eutectic solder bumps  
Ultra small footprint suitable for portable devices  
Lead-free version available  
The bump size and pitch of these filters are selected  
such that the device can be placed directly on an FR4  
printed circuit board using conventional assembly tech-  
niques. The pin-out for the device features a signal  
‘flow through’ design, allowing optimal PCB signal rout-  
ing. The solder bump contacts are a 63/37 Sn/Pb alloy  
(Sn/Ag/Cu for lead-free finish) and are 0.30 mm in  
diameter.  
Applications  
EMI filtering for RF sections of wireless devices  
Cellular phones  
Cordless phones  
Internet appliances  
PDAs  
Laptop computers  
The CM1300 incorporates OptiGuardTM coating which  
results in improved reliability at assembly. The device  
is available in a space-saving, low-profile Chip Scale  
Package with optional lead-free finishing.
