Philips Semiconductors
Product specication
UHF power LDMOS transistor
BLF861A
FEATURES
High power gain
Easy power control
Excellent ruggedness
Designed to withstand abrupt load mismatch errors
Source on underside eliminates DC isolators; reducing
common mode inductance
Designed for broadband operation (UHF band)
Internal input and output matching for high gain and
optimum broadband operation.
APPLICATIONS
Communication transmitter applications in the UHF
frequency range.
DESCRIPTION
Silicon N-channel enhancement mode lateral D-MOS
push-pull transistor in a SOT540A package with ceramic
cap. The common source is connected to the mounting
flange.
