Abstract: Provided is a Marchand balun and a frequency multiplier including the same. The Marchand balun may include transmission lines and slot lines extending to be proximate to the transmission lines. The transmission lines may include feeding transmission lines and coupled transmission lines connected to the feeding transmission lines. The slot lines may include near-distance slot lines provided to be adjacent to the feeding transmission lines, and far-distance slot lines extending in a direction away from the near-distance slot lines. The feeding transmission lines may be provided to be adjacent to the near-distance slot lines.
