E.2 Spurious emissions
05.053GPPRadio transmission and receptionTS
At maximum repeater gain, with or without a continuous static sine wave input signal in the operating band of the repeater, at a level which produces the manufacturers maximum rated power output, the following requirements shall be met.
The average power of any single spurious measured in a 3 kHz bandwidth shall be no greater than:
‑ 250 nW (‑36 dBm) in the relevant MS and BTS transmit frequency bands for a GSM repeater at offsets of > 100 kHz from the carrier.
‑ 1 W (‑30 dBm) in the relevant MS and BTS transmit frequency bands for a DCS 1 800 repeater at offsets of > 100 kHz from the carrier.
Outside of the relevant transmit bands the power measured in the bandwidths according to table E.1, shall be no greater than:
– 250 nW (‑36 dBm) in the frequency band 9 kHz to 1 GHz;
– 1 W (‑30 dBm) in the frequency band 1 GHz to 12,75 GHz.
Table E.1
Band | Frequency offset | Measurement bandwidth |
100 kHz ‑ 50 MHz | ‑ | 10 kHz |
50 MHz ‑ 500 MHz outside the relevant BTS transmit band or | (offset from edge of the relevant transmit band)‑ | |
MS transmit band | > 0 MHz | 10 kHz |
2 MHz | 30 kHz | |
5 MHz | 100 kHz | |
above 500 MHz outside the | (offset from edge of the | |
relevant BTS Transmit band or | relevant above band) | |
MS transmit band | > 0 MHz | 10 kHz |
2 MHz | 30 kHz | |
5 MHz | 100 kHz | |
10 MHz | 300 kHz | |
20 MHz | 1 MHz | |
30 MHz | 3 MHz |
The requirement applies to all ports of the repeater.
NOTE: For radiated spurious emissions, the specifications currently only apply to the frequency band 30 MHz to 4 GHz. The specification and method of measurement outside this band are under consideration.
