Using a 100 mA bias current, I get 53W output power with a 1W SSB-FM input power and a LPF in between. I consume 1.8 amps of power at 48 V. The transistor body and the heatsink are not overheated. Do I need to increase the bias current to 200 mA for a little more power?</P> Wed, 10 Sep 2025 11:14:19 GMT https://community.nxp.com/t5/Other-NXP-Products/mrf101/m-p/2166612#M29975 onder 2025-09-10T11:14:19Z https://community.nxp.com/t5/Other-NXP-Products/mrf101/m-p/2168038#M30004 <P>Hello Onder</P> <P>Good Day!</P> <P>Yes, you can increase the current up to 300mA, I just recommend that you do this process step by step, like 20mA-50mA, the first time to verify that the signal doesn't start to fluctuate.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="RafaR_0-1757614160971.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/356553iE188B206E8428392/image-size/medium?v=v2&amp;px=400" role="button" title="RafaR_0-1757614160971.png" alt="RafaR_0-1757614160971.png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">RafaR_0-1757614160971.png</span></span></P> <P>&nbsp;</P> <P>I hope this information has helped you, please let me know if you need help with anything else.</P> <P>Have a great day and best of luck.</P> Thu, 11 Sep 2025 18:10:00 GMT https://community.nxp.com/t5/Other-NXP-Products/mrf101/m-p/2168038#M30004 RafaR 2025-09-11T18:10:00Z
