50 Watts, 860–900 MHz

Cellular Radio RF Power Transistor

Description

The 20004 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 50 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.
