UHF power LDMOS transistor
BLF861A
APPLICATION INFORMATION
RF performance in a common source 860 MHz test circuit. Th =25 °C; Rth mb-h = 0.15 K/W; unless otherwise specied.
Note
1. Sync compression: input sync
≥ 33%; output sync 27% measured in an 860 MHz test circuit.
Ruggedness in class-AB operation
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.
