Very Compact Case (3U Rack)
H�gh Qual�ty Profess�onal DDS modulator w�th bu�lt �n RDS encoder
Very H�gh Eff�c�ency More Than 67%
Automat�c Power Control
Fully Broadband
Measurement And D�splay Of The Transm�tter's Work�ng Parameters
H�gh Rel�ab�l�ty Use Of M�crostr�p Technology
Compl�ant W�th All The Standard ETSI – CCIR - FCC
The FTC750 FM transm�tter �s des�gned to prov�de more rel�able FM transm�tters us�ng the LDMOS power
trans�stor for the FM broadcast market.
The ampl�f�er uses only 1 p�ece BLF578 extremely rugged LDMOS power trans�stor from NXP.
LDMOS technology allows h�gher performance compared to the trad�t�onal MOSFET trans�stors:
•
H�gher eff�c�ency (78%).
•
Excellent thermal stab�l�ty
•
Smaller d�mens�ons at the same RF output power.
