4.1.3. Tx Power
The following table shows the RF output power of EC21 series module.
Table 27: RF Output Power
Frequency Max. RF output power Min. RF output power
GSM850/EGSM900 33 dBm ±2 dB 5 dBm ±5 dB
DCS1800/PCS1900 30 dBm ±2 dB 0 dBm ±5 dB
GSM850/EGSM900 (8-PSK) 27 dBm ±3 dB 5 dBm ±5 dB
DCS1800/PCS1900 (8-PSK) 26 dBm ±3 dB 0 dBm ±5 dB
WCDMA bands 24 dBm +1/-3 dB < -49 dBm
LTE-FDD bands 23 dBm ±2 dB < -39 dBm
LTE-TDD bands 23 dBm ±2 dB < -39 dBm
In GPRS 4 slots TX mode, the maximum output power is reduced by 3.0 dB. The design conforms to the
GSM specification as described in Chapter 13.16 of 3GPP TS 51.010-1.
4.1.4. Rx Sensitivity
The following tables show the conducted RF receiving sensitivity of EC21 series module.
