The FT4K FM transmitter s designed to provide more reliable FM transmitters using the extremely rugged LDMOS power transistor for the FM broadcast market.
It has a 50W exciter (OM50), 4KW FM amplifer (FA4K) and a cabinet.
The amplifer uses only 4 peces BLF178XR extremely rugged LDMOS power transistor from NXP.
LDMOS technology allows hgher performance compared to the tradtonal MOSFET transstors:
• Higher effcency(72%).
• Excellent thermal stabilty
• The BLF178XR are capable of wthstandng a load msmatch correspondng to VSWR > 65 : 1.
Ths means that t s very hard to demage the transstor wth hgh reflecton from antenna.
• Smaller dimensions at the same RF output power.
