The QPQ1906 from Qorvo is a Bulk Acoustic Wave (BAW) Bandpass Filter with a passband from 2447 to 2472 MHz. It has an insertion loss of 1.1 dB in the passband and provides an attenuation of up to 57 dB above and below the passband. The filter has a VSWR of 1.5:1 and can handle up to 28 dBm of average input power.
The QPQ1906 has extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi band (Channels 10-11) and high near-in rejection in the 2.4 GHz higher frequency channels. The filter module is specifically designed to enable unique use cases where sub-dividing usable channels within the available Wi-Fi spectrum is an advantage. End users will have the ability to deliver Wi-Fi in channels 10 or 11 while providing rejection at higher frequencies to allow simultaneous use of Wi-Fi, Zigbee, Thread, or BLE channels.
This filter is available in a 2-pad surface-mount package that measures 1.6 x 2.00 mm and is suitable for applications such as access points, wireless routers, residential gateways, customer premise equipment, and IoT.
