• Manufacturer Part Number: ammp-6442
• Description: 37- 40 Ghz, 1w Linear Power Amplifier In Smt Package
• Manufacturer: Avago Technologies

Application and Usage
Recommended quiescent DC bias condition for optimum power and linearity performances is Vd=5 volts with Vg (-1V)
set for Id=700 mA. Minor improvements in performance are possible depending on the application. The drain bias
voltage range is 3 to 5V. A single DC gate supply connected to Vg will bias all gain stages. Muting can be accomplished
by setting Vg to the pinch-off voltage Vp (-2V).
A typical DC bias configuration is shown in Figure 13. Vd3 may be biased from either side (Pin 3 or Pin 5). The RF input
and output ports are DC decoupled internally. No ground wires are needed since ground connections are made with
plated through-holes to the backside of the device.

Figure 13. Schematic and recommended assemble example
Note: No RF performance degradation is seen due to ESD up to 250V HBM and 60V MM. The DC characteristics in general show increased leakage at
lower ESD discharge voltages. The user is reminded that this device is ESD sensitive and needs to be handled with all necessary ESD protocols.
