Description:
The NTE352 is a 12.5V Class C epitaxial silicon NPN transistor in a W65 type package designed
primarily for VHF, FM communications. Diffused emitter resistors provide high VSWR capability
under rated operating conditions. Internal impedance matching ensures optimum power gain and
efficiency over the 136−175MHz band.
