Description

PTB 20193

60 Watts, 1.8–1.9 GHz

Cellular Radio RF Power Transistor

The 20193 is a class AB, NPN common emitter RF power transistor
intended for 26 Vdc operation from 1.8 to 1.9 GHz. It is rated at 60
watts minimum output power and 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.
