QPF8538
Wi-Fi Front End Module
4900MHz to 5925MHz
®
Product Description
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
Package: Laminate, 16-pin,
2.3mm x 2.3mm x 0.63mm max
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 2.3mm x 2.3mm x 0.0.63mm, 16-pin
laminate package.
