TU-WTR-FP100 Radar Module Fully integrated stand-alone millimetre-wave FMCW Radar
Overview
The TU-WTR-FP100 radar module is a fully integrated stand-alone millimetre-wave
FMCW radar front end module designed for radar sensors and security systems. A
digital input is provided for control of the FMCW sweep characteristics/baseband
receive gain and the only output is a baseband beat frequency signal, the frequency
of which is proportional to distance. The standard RF transmit power is 40mW
with an option for 10mW. Operating at a centre frequency of 94GHz, this module
has substantial advantages over ~76GHz systems, taking advantage of the low
atmospheric attenuation ‘window’. It is especially suited to low visibility navigation
such as helicopter brownouts and marine fog environments.
The module contains Arralis Tucana monolithic millimetre wave P-HEMT integrated
circuits with separate power and microwave baseband boards with integrated swept
local oscillator and frequency references. Advantages include low frequency inputs,
WR10 connections, single rail power supplies and integration simplicity.
