PTB 20079
10 Watts, 1.6鈥?.7 GHz
INMARSAT RF Power Transistor
Description
The 20079 is a class A/AB, NPN, silicon bipolar junction, internally-
matched, common emitter RF Power transistor intended for 26 Vdc
operation across 1.6 to 1.7 GHz frequency band. It is rated at 10
Watts minimum output power for PEP applications. Ion implantation,
nitride surface passivation and gold metallization ensure excellent
device reliability. 100% lot traceability is standard.
