4.2 Transmitter Requirements

Where the transmitter is designed with adjustable carrier power, then all transmitter parameters should be measured using the highest power level. The spurious emissions should be measured at both the highest and the lowest carrier power settings.

If the equipment to be tested is designed with a permanent external 50 Ω RF connector and a dedicated or integral antenna, then full tests should be carried out using this connector. If the RF connector is not 50 Ω, then a calibrated coupler or attenuator should be used to provide the correct termination impedance to facilitate the measurements. The equivalent isotropically radiated power is then calculated from the declared antenna gain.

The following is a summary of the most important requirements for the transmitter in the 2.4 GHz and 5 GHz bands in EN 300 440.
