bandBoost BAW Filter Rejects Bluetooth

RFMW announces design and sales support for high-performance, high power, Bulk Acoustic Wave (BAW) band-pass filter. The Qorvo QPQ1905 exhibits low loss in the Wi-Fi band (Channels 1-2) and high, near-in rejection in the 2.4 GHz higher frequency channels allowing simultaneous use of Wi-Fi, Zigbee, Thread or BLE channels. Specifically designed to enable unique use cases where sub-dividing usable channels within the available Wi-Fi spectrum becomes an advantage, bandBoost enhances operation from 2402-2427 MHz while extremely steep filter skirts reject channels 10-11. With power handling to +28 dBm averaged input power, the QPQ1905 supports access points, wireless routers, residential gateways and customer premise equipment.
