The present document covers amplifiers and active antennas used for broadcast TV and sound reception at UHF (470 MHz to 790 MHz) and at VHF (174 MHz to 230 MHz). The present document applies to the domestic equipment types defined in table 1. Table 1: Equipment type definitions Equipment Type Description Notes P Preamplifiers Low noise amplifiers with one or more outputs. D Domestic amplifiers Amplifiers with one or more outputs not intended for low noise applications. L Launch amplifiers High output level amplifiers used for MATV systems. A Active antennas Amplified domestic antenna for indoor use. The selectivity classifications and associated RF environments are defined in table 2. Table 2: RF environment and selectivity classification Selectivity Classification Intended RF environment Notes 0 IMT is not deployed in the range from 694 MHz to 790 MHz. Devices have wideband response, with no selectivity. This classification is expected to have a limited lifetime and may be withdrawn subject to European decisions relating to the band 694 MHz to 790 MHz. Wideband components (e.g. launch amplifiers) may still be appropriate where filters are included elsewhere in the system. 1 IMT is deployed above 700 MHz (E-UTRA band 28 and band 20). Devices have selectivity to reject IMT signals above 700 MHz. Provides selectivity to reject LTE-700 (E-UTRA band 28) and LTE-800 (E-UTRA band 20) signals. 2 IMT is deployed above 700 MHz or below 470 MHz. Devices have selectivity to reject IMT signals below 470 MHz and above 700 MHz. Provides selectivity to reject LTE-700 (E-UTRA band 28), LTE-800 (E-UTRA band 20) and IMT signals below 470 MHz. The equipment type and selectivity classification appropriate for the RF environment are combined to define an equipment category. For example, equipment type P and selectivity classification 0 denotes a wideband preamplifier (equipment category P0) intended for use where IMT is not deployed in the range from 694 MHz to 790 MHz. The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
