Philips Semiconductors Objective specification
UHF power LDMOS transistor BLF2043
FEATURES
• High power gain
• Easy power control
• Excellent ruggednes s
• Source on mounting base eliminates DC isolators,
reducing common mode inductance
• Designed for broadband operation (HF to 2.2 GHz).
APPLICATIONS
• Communication transmitter applications in the UHF
frequency range.
DESCRIPTION
Silicon N-channel enhancement mode lateral D-MOS
transistor encapsulated in a 2-lead flangless package
(SOT538A) with a ceramic cap. The common source is
connected to the mounting base.
QUICK REFERENCE DATA
