The WLAN7205C from NXP reduces the number of components in the Wi-Fi RF signal chain.
With Wi-Fi 6E (5.925 MHz to 7.125 MHz) now approved, user equipment will need to support it. NXP’s WLAN7205C RF front end combines a power amplifier (PA), low-noise amplifier (LNA), DC blocking capacitors, switches, and decoupling capacitors in a single QFN package.
Covering 5.150 GHz to 7.125 GHz, which includes the 5 GHz Wi-Fi band, the WLAN7205C should find applications in portable devices such as smartphones tablets, and embedded systems. It’s 50 Ω RF impedance means it needs no external impedance-matching components. A SPDT switch connects the host device’s antenna to either the transmit or receive circuits. The WLAN7205C provides five transmit operation modes per band. Its two receive operation modes using a SPST switch enable a gain step between LNA mode and Bypass mode. Control signal levels support 1.2 V and 1.8 V logic interface up to 2.1 V of max input level.
