10 W (40 dBm) power output amplifiers in 1-20 MHz band

Hi Sanjmehta,

                     We  have not investigated performance or whether the part will operate below 10 Mhz. I do know that it was a challenge to match at the lower frequencies. So you might not be able to match below 10 Mhz.

 If it is not adequately matched you well get reflections and risk damage to the parts.

Hi Jim,

Thank you for the prompt response. When you mention matching at lower frequencies, is it internal or external matching. If it is external matching what kind of matching do you suggest for operational frequencies listed on the data-sheet?

Thanks,

Sanj

Hi Sanjmehta,

                        The device is externally matched. The attached pdf has the matching components circled in red.

We have not measured the part below 10 MHz. from the data we have the gain curve shows sharp roll off and matching gets worse.  suggesting the part will not work down to 1 MHz.
