THEORY OF OPERATION

The HMC8412 is a GaAs, MMIC, pHEMT, low noise wideband

amplifier with integrated ac-coupling capacitors and a bias

inductor. A simplified schematic is shown in Figure 59.

The HMC8412 has ac-coupled, single-ended input and output

ports with impedances that are nominally equal to 50 Ω over

the 0.4 GHz to 11 GHz frequency range. No external matching

components are required. To adjust the drain bias current,
