QPQ1289.
LTE扩展带4 /频段10 BAW双工器
主要特征
- 尺寸非常小（2.00 x 2.50 x 0.91 mm）
- 低插入损耗（2.0 dB，2.3 dB，典型值）
- 高拒绝
- 陡峭的裙子和低温漂移提供出色的Wi-Fi排斥
The QPQ1289 is a high performance Bulk Acoustic Wave (BAW) duplexer, designed for basestation uplink / downlink applications. The device’s low insertion loss and high attenuation make it ideal for small cells.
The duplexer is designed using BAW filters that provide very steep skirts and low temperature drift, allowing excellent rejection of Wifi and other interfering signals. It is housed in a compact, RoHs-compliant 2.00 mm x 2.50 mm x 0.91 surface mount package (SMP).
