The IC modules TRX_024_006 and TRX 024_007 are compact analogue radar front ends for the license-free ISM band between 24.00 and 24.25 GHz. To fit a broad range of applications they can be operated in CW and FMCW mode. Their main application is in short range devices (SRD) with distances of up to 20 meters. This operation distance can be increased up to 200 meters for a set-up with beam lens. Another domain of deployment is for (tank) level probing radar (T)LPR.
Both, TRX_024_006 and TRX 024_007 feature two levels of amplification and gain which can be selected via control pins for the transmitter as well as the receiver branch, respectively. A separate output provides a frequency reference of the internal VCO at a ratio of 1:32 (TRX_024_006) or 1:8 (TRX_024_007) of the fundamental frequency. This allows e.g. to optimize the set-up for a deployment of cost efficient PCB materials.
The transmission of these radar MMICs can be switched off using an enabling pin in the tx branch. Minimum power consumption is achieved in operation modes with low duty cycles and short ramp up times of down to 100 μs.
