scope:

The present document applies to Short Range Devices (SRDs) transmitters and receivers for RTTT applications:

a) transmitters operating in range from 76 GHz to 77 GHz with peak power levels ranging up to 55 dBM;

b) receivers operating in the range from 76 GHz to 77 GHz;

c) transmitters operating in range from 24,050 GHz to 24,250 GHz with peak power levels ranging up to 20 dBm;

d) transmitters operating in range from 22,625 GHz to 24,050 GHz and 24,250 GHz to 25,625 GHz with power levels ranging up to -30 dBm;

e) receivers operating in the range from 22,625 GHz to 25,625 GHz.

The present document contains the technical characteristics for radio equipment and is referencing to CEPT/ERC Recommendation for SRDs CEPT/ERC Recommendation 70-03 [4] and ERC Decisions.

The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.

The present document applies to:

- low power motion and distance monitoring radars for mobile and fixed applications; operating on radio frequencies in the 76 GHz to 77 GHz band, with mean power densities of up to 0,9 W/m² at 3 m (50 dBm EIRP), and up to 3 W/m² peak at 3 m (55 dBm EIRP) for class 1, and mean power densities of up to 0,002 W/m² at 3 m (23,5 dBm EIRP), and up to 3 W/m² peak at 3 m (55 dBm EIRP) for class 2.

- ultralow power motion and distance monitoring radars for mobile applications; operating on radio frequencies in the 22,625 GHz to 25,625 GHz band with a maximum spatial mean/peak power density of up to 0,9 mW/m² at 3 m (20 dBm EIRP) in the 24 GHz SRD band. and with spectral adn spatial mean power densities of up to 9 n W/m² at 3 m (-30 dBM EIRP @ 100 kHz RBW, PSD < -80 dBm/Hz) within a range of 2 x 2,5 GHz outside the 24 GHz SRD band.

The present document is based upon ERC/DEC/(92)02 [5] It is a product standard covering various RTTT applications.

The present document is essential in realization of the ITS program of the European Commission Information Society DG, "The EU Approach for Road Safety and Intelligent Transport Systems(ITS)", [6].

The present document covers radars for mobile applications. It covers integrated transceivers and separate transmit/receive modules.

The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [1] (R&TTE Directive),

In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present document.
