Abstract

This paper presents an approach to designing a modulator based on a Ku-band low-voltage double-output magnetron. The frequency tuning is achieved using a varactor that acts as a reactive load for the passive RF output of the magnetron. It shows that frequency modulation can be achieved with a maximum frequency deviation of 50 MHz, covering the frequency range of 13.05 to 13.55 GHz. The primary feature of the proposed method is its straightforward and reliable design, which minimizes weight and volume while delivering a carrier signal output power of ~ 15 W and stability no worse than ~ 10-6.
