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.
