CM1300 4 Channel EMI Filter Network Features Product Description • • 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 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. • • • • • • • Functionally and pin compatible with CSPRC032A 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 Applications • • • • • • EMI filtering for RF sections of wireless devices Cellular phones Cordless phones Internet appliances PDAs Laptop computers Electrical Schematic A1 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 techniques. The pin-out for the device features a signal ‘flow through’ design, allowing optimal PCB 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 diameter. 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. 50Ω 50Ω R A2 50Ω C R 43pF GND R 50Ω 50Ω GND B3 50Ω 50Ω B4 C R 43pF R A5 B2 C R 43pF GND A4 B1 GND R 50Ω B5 C R 43pF GND © 2005 California Micro Devices Corp.
