Chip filter shrinks size for cellular band apps

Chip filter shrinks size for cellular band apps

Offered as one of the smallest chip filters in its class, the FI168D087018 EIA 0603 size dual low-pass filter measures just 1.6 x 0.8 x 0.45 mm and targets multiband smartphones. Smartphones equipped with dual low-pass filter technology meet the wireless communication standards that are required to achieve high-speed data transmission.

Two differing frequency-band low-pass filters are combined into a single part. LPF features for low-frequency band include a passband frequency of 824 to 915 MHz, while LPF features for high-frequency band include a passband frequency of 1,710 to 1,919 MHz.

Also announced are the EIA 0805 size FI212P089208 and FI212P089213 multilayer diplexers, measuring 2.0 x 1.25 x 0.90 mm each and optimized for the RF send/receive systems of multiband mobile phones. The diplexers have a low-frequency passband frequency of 824 to 960 MHz, and a high-frequency a passband frequency of 1,710 to 2,170 MHz. (Each device, $0.50 ea/sample price — available now.)
