Qorvo QM42655 Wi-Fi® 7 Front End Module (FEM)
Qorvo QM42655 Wi-Fi® 7 Front End Module (FEM) offers integration developed for Wi-Fi 7 (802.11be) systems. The QM42655 allows for a minimal layout area with integrated matching and a small form factor. The PA is optimized for a broad (3.0V < Vcc < 5.0V) supply voltage range.
The QM42655 FEM provides multiple Wi-Fi and BT TX modes that facilitate the optimization of output power, linearity, and power dissipation. These features conserve power consumption while preserving the highest linear output power and leading edge throughput.
The mobile Qorvo QM42655 integrates a multi-TX-state 2.4GHz Wi-Fi power amplifier (PA) that is also used for HP BT, a single-pole four-throw switch (SP4T) ANT switch, a bypassable low-noise amplifier (LNA) with multiple RX states, and a power coupler into a single device.
