designed for Wi-Fi 802.11ax systems. The compact form factor
and integrated matching minimizes layout area in the
application.
Performance is focused on optimizing the PA for a 5V supply
voltage that conserves power consumption while maintaining
the highest linear output power and leading edge throughput.
Receive path matches the optimal technologies to maximize Rx
sensitivity through noise figure performance that is consistent
over a wider variety of conditions.
Integrated die level filtering for 2nd and 3rd harmonics as well
as 5 GHz rejection for DBDC operation are included.
The QPF4200 integrates a 2.4 GHz power amplifier (PA),
regulator, single pole two throw switch (SP2T), bypassable low
noise amplifier (LNA) and DC power detector into a single device
