Signal distribution system, and related phased array radar system

A phased array radar system, comprising:

• a first RF device, the first RF device comprising a first signal divider arranged to generate a first output oscillating signal according to a first input oscillating signal;
• a second RF device, the second RF device comprising a second signal divider, arranged to generate a second output oscillating signal according to the first input oscillating signal;
• a first transmitting channel, coupled to the first signal divider and the second signal divider, for transmitting the first input oscillating signal to the first signal divider and the second signal divider;
• and
• a second transmitting channel, coupled to the first signal divider and the second signal divider, for transmitting a second input oscillating signal to the first signal divider and the second signal divider;
• wherein the first input oscillating signal has a first frequency, the second input oscillating signal has a second frequency, and the second frequency is smaller than the first frequency.
