M50 Hardware Design
M50_HD_V2.0 - 72 -
GSM850/EGSM900 is <1dB.
DCS1800/PCS1900 is <1.5dB.
4.2. RF output power
Table 31: The module conducted RF output power
Frequency Max Min
GSM850 32.5dBm ±1dB 5dBm±5dB
EGSM900 32.5dBm ±1dB 5dBm±5dB
DCS1800 29.5dBm ±1dB 0dBm±5dB
PCS1900 29.5dBm ±1dB 0dBm±5dB
Note: In GSM850&EGSM900 GPRS 4 slots TX mode, the max output power is reduced by
2.5dB. This design conforms to the GSM specification as described in section 13.16 of 3GPP TS
51.010-1.
