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 - 25d B 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 techniques. 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 diameter. 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. Electrical Schematic A1 50Ω 50Ω B1 R CR 43p...
