PLT03-601L

 

General information

Designed for analog and digital TV transmitters and transposers this RF amplifier incorporates, simple design based on microstrip and stripline technology, PTFE PCB, planar balun and pushpull LDMOS to enhance ruggedness and reliability. Very low thermal resistance is obtained by means of a silver plated copper base‐plate coupled with latest generation printed circuit board material and devices. The RF block amplifier (pallet) is easy replaceable without any soldering and alignment, it comprises circuits for stabilising the operating point and current monitoring readout.
