Title:
BROADBAND FREQUENCY DETECTOR
Document Type and Number:
WIPO Patent Application WO/2014/107089
Kind Code:
A1
Abstract:
The present invention relates to a broadband frequency detector and, more specifically, to a frequency detector for detecting all signals for inducing the safe driving of a vehicle and radar signals for determining the speed of the vehicle. To this end, the broadband frequency detector according to the present invention comprises: a horn antenna for receiving a signal having a predetermined frequency; a first amplifier for receiving the signal having a predetermined frequency from the horn antenna; a mixing unit for receiving, from the first amplifier, the signal which has been low-noise amplified by the first amplifier; and a second amplifier which is disposed in parallel with the first amplifier and low-noise amplifies the signal received from the horn antenna so as to relay same to the mixing unit, wherein the second amplifier comprises a transistor and a first micro-circuit unit for matching the impedance of the horn antenna to the impedance of the transistor.
