Product specication
NPN 2 GHz RF power transistor
BFG11; BFG11/X
APPLICATION INFORMATION
RF performance at Tamb =25 °C in a common-emitter test circuit (see Fig.7).
Ruggedness in class-AB operation
The BFG11 is capable of withstanding a load mismatch corresponding to VSWR = 8 : 1 through all phases, at rated
output power under pulsed conditions up to a supply voltage of 8 V, f = 1.9 GHz and a duty cycle of 1 : 8.
