Description
PTB 20046
1 Watt, 1465–1513 MHz
Cellular Radio RF Power Transistor
The 20046 is a class AB, NPN, common emitter RF power transistor
intended for 26 Vdc operation from 1465 to 1501 MHz. Rated at 1
watt 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.
