Product Description
The CM1300 is a 4-channel low pass EMI filter (R-C-R
configuration) in a Chip Scale Package (CSP). Many
portable applications require the attenuation 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.
The bump size and pitch of these filters are selected
such that the device can be placed directly on a FR4
printed circuit board using conventional assembly tech-
niques. The pin-out for the device features a signal
‘flow through’ design, allowing optimal signal routing.
The solder bump contacts are a 63/37 Sn/Pb alloy (Sn/
Ag/Cu for lead-free finish) and are 0.30 mm in diame-
ter.
The CM1300 incorporates Optiguard
TM
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.
