UHF Load Based on Reflection Less Filter

Decimeter range wide-band UHF load based on reflection less low-pass filter and high power planar film resistors is considered. Significant load operation frequency range extension is achieved owing to additional ballast resistors consuming UHF power outside the low-pass filter frequency band. The designed load ensures UHF power dissipation of 200 W within the frequency range 0-2000 MHz and can be used in radio-transmitting equipment for digital TV broadcasting and telecommunications systems.
