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. 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. 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.
