Figure 3. PCB Pad Print for Minipak 1412.
Package (mm [inches ]).
This pad print provides allowance for
package placement by automated
assembly equipment without adding
excessive parasitics that could impair
the high frequency performance of
the ATF-541M4. The layout is shown
with a footprint of the ATF-541M4
superimposed on the PCB pads for
reference.
For Further Information
The information presented here is an
introduction to the use of the ATF-
541M4 enhancement mode PHEMT.
More detailed application circuit in‑
formation is available from Avago
Technologies. Consult the web page
or your local Avago Technologies sales
representative.
