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!
