DESCRIPTION
200
AMCOM’s AM005WX-BH-R is a discrete GaAs pHEMT
that has a total gate width of 0.5mm. It is in a ceramic BH
package for operating up to 12GHz. The BH package
has all leads bent in a surface mounting style on PC
Board. The bottom of the package serves simultaneously
as DC ground, RF ground, and thermal path. For
frequencies above 5GHz, we recommend to mount the
device directly on a metal heat sink, which is also RF
ground, to avoid the inductance of PCB via holes. This
part is RoHS compliant.

MOUNTING INSTRUCTIONS
The device may dissipate several watts of power. It is important to provide a good heat sink to dissipate the heat.
There are two options of mounting the amplifier, as shown. The most effective way is to mount the amplifier to a
heat sink pedestal (Option 1). We strongly recommend this way for high power device. The other option, which is
mounted directly on PCB, is to add sufficient number of plated through via holes to the PCB. The base of the
device is soldered to the PCB (Option 2). The via hole wall should be plated by at least 1 oz thick (1.5 mil) of high
thermal conductivity copper to conduct the heat from the top of PCB to the bottom of PCB. Also fill the via holes
with solder to help conducting the heat.
