Wafer Level Package Evaluation RC Filter Network
Features
6 Filters per device
Ultra small footprint, 0.5mm pitch
Silicon substrate
0.30mm Eutectic Solder Bumps
Product Description
The WLP200 consists of 6 RC filters with different filter
characteristics in a wafer level package (WLP). All
I/O pins are ESD protected for contact discharges up to
8KV per the IEC1000-4-2 level 4 specification. Two
versions with different capacitor values are available.
Cellular phone application frequently demands filtering
of signals in the 800 to 2,700 MHz band. California
Micro Devices’ unique thin film Flip Chip filters provide a
minimum of –30 dB of attenuation over this frequency
Applications
EMI filter for Mobile Equipment
(e.g. Cellular Phones)

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. Ground-bounce and cross-talk are mini-
mized by a die design that provides eight solder bump
contacts to the common supply connection. The solder
bump contacts are a 63/37 Sn/Pb alloy and are nomi-
nally 0.30 mm in diameter.
