Description

The 20204 is a class A, NPN, common emitter RF power transistor
intended for 24 Vdc operation from 380 to 500 MHz. Rated at 1.0
watt minimum output power, it may be used for both CW and PEP
applications. Ion implantation, nitride surface passivation and gold
metallization ensure excellent device reliability. 100% lot traceability
is standard.
