The advantages of Freescale LDMOS

• Super rugged with mismatch tolerance up to VSWR 65:1;

• Withstand 3dB over-driver under 17VDS;

• -50% Rth due to Freescale advance package technology;

• Airfast technology gives +20% power density, +5% efficiency and

+4dB gain;

• Lower frequency disperse, easier matching.

AFT05MP075 Impedance– easier for matching!

440 0.63 -0.99 1.6

470 0.52 -0.83 1.6 500 0.8 -0.1 0.1

• The Q factor of Zsource (Real/Imag) is less than 2. It makes 20% bandwidth matching quite easy!

• The Zload varies slowly across the 100-500MHz band, which makes the wideband matching easily.

• In a nutshell, AFT05MP075 can save you a lot of tuning time!
