Description
M/A-COM’s PH11819-45A is a high efficiency silicon bipolar NPN transistor intended for use as a common emitter
class AB stage in power amplifiers that operate in the 1805
to 1880 MHz range. This transistor features internal input
and output impedance matching, diffused emitter ballasting
and gold metalization. The PH1819-45A is packaged in a
low cost, non-hermetic ceramic package which has a very
low thermal impedance.
