ROHS COMPLIANT

This device is part of Polyfet's latest

family of 28VDC LDMOS devices.

Being an unmatched device and

having low capacitances makes it

ideal for broad band applications

such as communications and

broadcast. It is also suitable for

various narrow band applications.

Employing back-to-back gate diodes

for enhanced ESD protection and

having a high drain breakdown

voltage makes this device highly

rugged. The suitable frequency range

of this device is 1-1100MHz
