At the same time, the amplifier can operate only in one of the GSM or DCS bands, for each of which there is a separate RF input. The amplifier has two equivalent RF outputs, switching between which is carried out using a logic control signal. The output SWR is monitored, if exceeded, a logic signal is sent to the control connector. Temperature compensation of the amplifier parameters has been implemented. APPLICATION Amplification of radio signals of transmitters of base stations of cellular systems An integral part of a cellular repeater MAIN TECHNICAL CHARACTERISTICS GSM channel GSM channel operating frequency range from 935 to 960 MHz Maximum output power (compression point at 1 dB level) in the GSM frequency range not less than 43 dBm Gain in the GSM frequency range not less than 28 dB Unevenness of the gain in the operating frequency range of the GSM channel 0.5 dB Harmonic level for 2nd and higher harmonics less than -50 dBc Consumption current at maximum output power supply voltage +28 V no more than 2.5 A The time of switching from the “off” mode to the “GSM amplification” mode is no more than 10 ms Time of switching from the “DCS amplification” mode to the “GSM amplification” mode, no more than 10 ms DCS channel DCS channel operating frequency range from 1805 to 1880 MHz Maximum output power (1 dB compression point) in the DCS frequency range not less than 43 dBm Gain in the DCS frequency range not less than 27 dB Gain flatness in the operating frequency range of the DCS channel 0.6 dB Harmonic level for 2nd and higher harmonics less than -50 dBc Consumption current at maximum output power supply voltage +28 V not more than 3.8 A The time of switching from the “off” mode to the “DCS amplification” mode is no more than 10 ms Time of switching from the “GSM amplification” mode to the “DCS amplification” mode, no more than 10 ms Download detailed description Request information | ABOUT THE COMPANY | | PRODUCTS | | TECHNOLOGIES | | SUPPORT |
