Description
PTB 20006
4 Watts, 860–900 MHz
Cellular Radio RF Power Transistor
The 20006 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 4 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.
