Compact form factor and integrated matching minimises layout area for signal transmission and receiving applications
RFMW announces design and sales support for Wi-Fi 5 (802.11ax) front end module (FEM). The Qorvo QPF4219 optimises the power amplifier for 5V operation while maintaining linear output power and leading-edge throughput.
The receive path maximises Rx sensitivity through noise figure performance that is consistent over a wider variety of conditions. External filtering can be added while integrated die level filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are included.
The QPF4219 integrates a 2.4 GHz power amplifier, regulator, single pole two throw switch (SP2T), bypassable low noise amplifier (LNA) and DC power detector into a single device.
It is designed for access points, wireless routers, residential gateways and CPEs in the 2400 to 2500 MHz frequency range,
- 33 dB of Tx gain and 15.5 dB of Rx gain
- Noise figure is 1.9dB
This FEM comes in a 5 x 3 mm package.
