7.3 Ruggedness in class-AB operation
The BLF881 and BLF881S are capable of withstanding a load mismatch corresponding to
VSWR = 10 : 1 through all phases under the following conditions: VDS = 50 V;
f = 860 MHz at rated power. Ruggedness is measured in the application circuit as
described in Section 8.
