Zusammenfassung:Provided is a broadband frequency detector, more particularly, to a frequency detector detecting all the signals for guiding the safe vehicle operation, and radar signals for determining vehicle speeds. The broadband frequency detector comprises: a horn antenna configured to receive signals having specific frequencies; a first amplifier configured to receive the signals having specific frequencies from the horn antenna; a mixer unit configured to receive signals from the first amplifier, wherein the signals are low noise amplified therein; and a second amplifier, arranged in parallel with the amplifier, for transferring signals to the mixer unit after low noise amplifying the signal received from the horn antenna, wherein the second amplifier includes a transistor.
