Wireless Power Transistor
45 Watts, 1805 - 1880 MHz
Features
• NPN Silicon Microwave Power Transistor
• -28 dBc Typical 3^rd IMD at 45 Watts PEP
• Common Emitter Class AB Operation
• Internal Input and Output Impedance Matching
• Diffused Emitter Ballasting
• Gold Metalization System
Description
M/A-COM’s PH11819-45A is a high efficiency silicon bipo-
lar 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.
