Application Requirements

Select filters per band plan, Tx/Rx duplexing and co-existence needs.

Center Frequency

700MHz~3000MHz covers mid-to-low band filtering for wireless communications.

Bandwidth

Flexible passband design from narrow-band to wide-band for GSM/WCDMA/LTE and Wi-Fi front ends.

Insertion Loss

Typical below 2.0dB keeps receiver sensitivity and transmitter efficiency high.

Selectivity

High rejection of out-of-band signals protects the RF chain from interference.

Impedance

50Ω nominal matching simplifies front-end design.

Package Size

Multiple SMD sizes (1109 to 3030) support compact module integration.
