70 Watts, 925–960 MHz
Cellular Radio RF Power Transistor
Description
The 20219 is a class AB, NPN common emitter RF power transistor
intended for 26 Vdc operation across the 925 to 960 MHz frequency
band. It is rated at 70 watts minimum output power for both CW and
PEP applications. Ion implantation, nitride surface passivation and
gold metallization are used to ensure excellent device reliability. 100%
lot traceability is standard.
