THEORY OF OPERATION

The HMC8413 is a GaAs, MMIC, pHEMT, low noise wideband

amplifier. Figure 70 shows the simplified architecture of the

HMC8413.

The HMC8413 has single-ended input and output ports with

impedances that nominally equal 50 Ω over the 0.01 GHz to

9 GHz frequency range. Therefore, the HMC8413 can be directly

inserted into a 50 Ω system with no required impedance

matching circuitry, which also means that multiple HMC8413

amplifiers can be cascaded back to back without the need for

external matching circuitry.

It is critical to supply very low inductance ground connections

to the ground pins as well as to the backside exposed pad to

ensure stable operation.

To achieve optimal performance from the HMC8413 and

prevent damage to the device, do not exceed the absolute

maximum ratings.

The RBIAS pin is used to set the IDQ with an external resistor,

allowing single positive supply operation.
