(20) 802.11b/g Band Pass Filter (SCI-303 W/F) FEATURES • Passive integration on silicon substrate • Low insertion loss in pass band • Small size: 1.3 mm x 0.9 mm (wirebond) 1.4 mm x 1.1 mm (flip chip) • Pb-free solder bump • Low profile: 0.25 mm height (wirebond) 0.40 mm height (flip chip) • Directly attachable on PCB or flipped on PCB • Operating temperature: -40℃ to +85℃ • Storage temperature: -40℃ to +85 ℃ DESCRIPTION STATS ChipPAC’s SCI-303W/F is a band pass filter (BPF) for 802.11b/g band applications. The BPF has low pass–band insertion loss and small size. It is composed of thick copper inductors and MetalInsulator-Metal capacitors which are fabricated on a silicon substrate using STATS ChipPAC’s IPD (Integrated Passive Device) process. The pad or bump size and pitch of the BPF are selected so that the device can be mounted directly on a PCB or laminate substrate using conventional wirebonding or surface mount techniques. The low profile and small formfactor of the device make it especially suitable for SiP applications. SCI-303W (Wirebond) SCI-303F (Flip Chip) ELECTRICAL SPECIFICATIONS Specification Unit Min.
