RF Power LDMOS Transistor
High Ruggedness N--Channel
Enhancement--Mode Lateral MOSFET
MRFE6VS25LR5
RF power transistor designed for both narrowband and broadband ISM,
broadcast and aerospace applications operating at frequencies from 1.8 to
2000 MHz. This device is fabricated using Freescale’s enhanced ruggedness
platform and is suitable for use in applications where high VSWRs are
encountered.
