°
C in a common-emitter test circuit.
Ruggedness in class-AB operation
The BFG10W/X is capable of withstanding a load mismatch corresponding to VSWR = 6 : 1 through all phases under
pulsed conditions up to a supply voltage of 8.6 V under the conditions: 900 MHz; 650 mW; t
p
= 4.6 ms; duty cycle of 1 : 8
and up to a supply voltage of 5.5 V under the conditions: 1.9 GHz; 200 mW; t
p
= 10 ms; duty cycle of 1 : 2.
