Why Are Application and Fractional Bandwidth Fundamental to Choosing an RF Amplifier?
Depending on the specifics of a particular amplifier application, there can be many critical RF parameters, including gain, P1dB, IP3, IP2, NF and efficiency. One fundamental requirement that is often overlooked, at least initially, is the application bandwidth.

Why Is the DFN-6 Package So Magnificent? Part 2
As we discussed in last month's newsletter, the Guerrilla RF DFN-6 portfolio currently offers a growing tool kit of 20+ devices which employ an identical package, pin out and layout. Selecting a different device and changing a component value, or sometimes placing or not placing a specific matching component, opens up a wide range of gain, NF, linearity and bypass options.

How Do I Improve Gain Flatness Without Sacrificing Return Loss?
Your broadband application requires a highly efficient, linear driver that features superior gain flatness with excellent return losses over the band. The return loss requirement prevents the use of mismatch at the low end of the band to flatten the gain, so what do you do?
