LR2501
General Description
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
