PTB 20009
2.5 Watts, 935–960 MHz
Cellular Radio RF Power Transistor
Description
The 20009 is a class AB, NPN, common emitter RF power transistor
intended for 24 Vdc operation across the 935 to 960 MHz frequency
band. Rated at 2.5 Watts minimum output power, it may be used 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.
