7 Channel LCD Filter Array with ESD Protection
Figure 1 Schematic
Description
BGF108L is a 7 channel 5th order LC filter array to provide superior signal attenuation in the 800 - 2200 MHz
range. EMI filtering is very good regarding suppression of interference caused by high power TX signals or
interference to RX frequency bands caused by data signal harmonics in mobile phones.
All pins are protected against ESD of ±15 kV according to IEC61000-4-2 (contact discharge). The wafer level
package is a green package with a size of only 2.1 mm x 1.7 mm and a total height of 0.6 mm.
Feature
• 7 channel integrated 5th order LC filter array
• Enhanced filtering of mobile phone frequencies by LC filter
• ESD protection of ±15 kV contact discharge on all IOs
according to IEC61000-4-2
• Wafer Level Package with SnAgCu solder balls
•400 µm solder ball pitch
• RoHS and WEEE compliant package
