The QPQ1905 from Qorvo is a BAW Bandpass Filter with a passband from 2402 to 2427 MHz. It can handle up to 28 dBm of average input power, has an insertion loss of 1.1 dB and provides an attenuation of up to 60 dB from 2447 to 2471 MHz. The filter has a VSWR of 1.3:1 and a return loss of less than 21.5 dB.
The QPQ1905 is a Bulk Acoustic Wave (BAW) band-pass filter with extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi band (Channels 1-2) 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 becomes an advantage. End users will see the capability to deliver Wi-Fi in channels 1 or 2 while providing rejection in higher frequencies to allow simultaneous use of Wi-Fi, Zigbee, Thread, or BLE channels.
The filter is available in a 2-pad surface mount package that measures 1.69 x 2.00 x 0.915 mm and is suitable for applications such as Access Points, Wireless Routers, Residential Gateways, Customer Premise Equipment, and IoT.
