ERICSSON PTB20248

PTB 20248
0.7 Watts, 1465–1513 MHz
Cellular Radio RF Power Transistor
Description
The 20248 is a class A, NPN, common emitter RF power transistor
intended for 26 Vdc operation from 1465 to 1513 MHz. Rated at 0.7
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.
