Description

PTB 20030

15 Watts, 420–470 MHz

RF Power Transistor

The 20030 is a class AB, NPN, common emitter RF power transistor
intended for 24 Vdc operation across the 420 to 470 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.
