Drain bias requires RF choke for efficiency. Amplifier must provide DC blocking at input and output. You can find reference circuits in the device datasheet.</P> <P>Best Regards,</P> <P>Pavel</P> <P>NXP TIC</P> <P>&nbsp;</P> Thu, 01 Oct 2020 18:29:01 GMT LPP 2020-10-01T18:29:01Z https://community.nxp.com/t5/Wireless-MCU/AFM907N-Biasing/m-p/1160947#M10214 <P>Hi There,</P><P>I would like to know if external DC blocking and RF choke are necessary for biasing the part.&nbsp;</P><P>&nbsp;</P><P>Thanks in advance</P><P>Adnan</P> Wed, 30 Sep 2020 00:44:58 GMT https://community.nxp.com/t5/Wireless-MCU/AFM907N-Biasing/m-p/1160947#M10214 AdnanK 2020-09-30T00:44:58Z https://community.nxp.com/t5/Wireless-MCU/AFM907N-Biasing/m-p/1161993#M10224 <P>Yes, this device needs gate and drain biasing.
