BLF888A



Features

  • Designed for broadband operation (470 MHz to 860 MHz)
  • Excellent ruggedness (VSWR ≥ 40 : 1 through all phases)
  • Extremely high power (P1dB 600W)
  • Internal input matching for high gain and optimum broadband operation
  • Optimum thermal behavior and reliability, Rth(j-c) = 0.15 K/W



A 600W LDMOS RF power transistor for DVB-T applications optimised to give most rugged performance with no compromise in broadband efficiency and gain.
