Product Description
techniques. The pin-out for the device features a signal
‘flow through’ design, allowing optimal signal routing.
Ground-bounce and cross-talk are minimized via a die
design that provides two solder bump contacts to the
common supply connection. The solder bump contacts
are a 63/37 Sn/Pb alloy and are nominally 0.35 mm in
diameter.
Many portable applications frequently demand filtering
of signals in the 800-2,700 MHz band. California Micro
Devices’ unique thin film Flip Chip filters provide a
minimum of –30 dB 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
