rf power amplifier - Jan Jenca co.

UHF Band power amplifier 90W + 30W

CH 21...CH60 - DVB-T power amplifier

LD MOSFET lnear power amplifier for UHF Band

Amplifiers are highly linear LD MOSFET (operation in class A or AB) suitable for all kinds of digital and analog modulation. They have control the transmitted output power, over and reverse polarity voltage protection, measure indoor temperature (° C for all models ), single DC supply 48V DC. Other frequencies and wattages upon request.
