TitleRF Front End WiFi FEM NF 2.5dB 3.3V RX Gain 12.5dB
Description

Qorvo QPF8538 Wi-Fi Front End Module provides a complete integrated solution for Wi-Fi 802.11a/n/ac systems. The QPF8538 has a small form factor and integrated matching minimizes layout area in the application. This greatly reduces the number of external components. Performance is focused on a balance of efficiency to linear power that increases the range and throughput of connections. Control lines are reduced to a two-line control scheme. The QPF8538 integrates a 5GHz power amplifier (PA), single-pole two-throw switch (SP2T) and a low noise amplifier (LNA) with bypass. Integrated filtering includes 2nd and 3rd harmonic as well as 2.4GHz rejection for dual-band dual-concurrent operation. A DC power detector is integrated for application calibration enablement. The device is provided in a 2.3x2.3x0.0.63mm, 16-pin laminate package.

Features, Applications

The QPF8538 provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11a/n/ac systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. Performance is focused on a balance of efficiency to linear power that increases the range and throughput of connections. Control lines are reduced to a two-line control scheme The QPF8538 integrates a 5GHz power amplifier (PA), single-pole two-throw switch (SP2T) and a low noise amplifier (LNA) with bypass. Integrated filtering includes 2nd and 3rd harmonic as well as 2.4GHz rejection for dual-band dual-concurrent operation. A DC power detector is integrated for application calibration enablement. The device is provided 0.0.63mm, 16-pin laminate package.
