Application Note on Sample Board Operation of the  
MASW-000834-13560T T/R Switch  
M/A-COM Products  
REV.3  
The following is an application guide for utiliza-  
tion of the MASW-000834-13560T in conjunc-  
tion with a supplied sample board from M/  
ACOM. The guide will review the operation of  
the T/R using a single positive supply as well as  
other optional dual polarity supplies.  
The MASW-000834-13560T is a T/R switch  
with two PIN diodes in series in a common an-  
ode configuration and one PIN diode in shunt on  
the Rx path. The switch die along with select  
matching components are mounted in a standard  
4mm MLP 16 lead package (Figure 1). The  
Figure 1. Package Outline Drawing  
switch die utilizes  
M/ACOM’s patented  
HMICprocess. The backside of the switch die  
is thermally grounded while electrically iso-  
lated. The excellent power handling of the die is  
achieved through specific techniques using  
unique thermal conductive epoxy embedded in  
the die. This allows the heat to be transferred  
from the series connected device to ground  
while maintaining electrical isolation. The large  
backside of the pad of the package is both  
thermal and electrical ground. Figure 2 shows  
the electrical/ thermal schematic of the device.  
The sample board is made of Rogers RO4350  
material 10mils thick dielectric with added lay-  
ers to increase the board thickness to 62mils for  
handling, rigidity and connector mounting.  
There are on-board bias networks incorporated  
to accommodate biasing the device without the  
use of expensive external bias tees. Figure 3  
shows the standard board layout with compo-  
nent selection for optimized performance up to 6  
GHz.
