NXP Semiconductors BLF861A
The BLF861A is capable of withstanding a load mismatch corresponding to VSWR = 10 : 1 through all phases under the following conditions: VDS = 32 V; f = 860 MHz at rated load power. The BLF861A is an improved version of the BLF861 on ruggedness and is capable to withstand abrupt source or load mismatch errors under the nominal power condition.| Part No. | BLF861A |
