PTB 20005
15 Watts, 860–900 MHz
Cellular Radio RF Power Transistor
Description
The 20005 is a class AB, NPN, common emitter RF power transistor
intended for 25 Vdc operation across the 860 to 900 MHz frequency
band. Rated at 15 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.
