MMDS Transmitter
Antenna MMDS :
The Outdoor MMDS Transmitter is intended for use in the MMDS, WI-FI and other system operating in 2300 to 2700 MHz frequency range . It is available in configurations of 20, 50, 100 Watt. The transmitter supports all modulation schemes (both analogous and digital ones). It features an RF Muting, which engages whenever IF signal at the Transmitter input becomes lower than the IF threshold level. A Thermal Shutdown feature, which is incorporated for the transmitter protection, disables the transmitter whenever its base plate temperature exceeds a temperature limit. An overpower shutdown feature disables the amplifier whenever the RF output power is detected to exceed an overpower limit. Built-in automatic gain control system provides nominal value of output signal. The transmitter construction consists of 2 modules: the transmitter itself located near transmitting antenna and power module which supplies power to the transmitter and its remote control unit. The remote control unit provides monitoring of the transmitter statuses. It display status of input and output signal; local oscillator; power amplifier; thermal and overpower shutdown; cooling fan. Technical parameters: • Output power at 1 dB gain compression 25W/50W/100W • Output frequency range 2300-2770 MHz • Bandwidth 200 MHz • Input frequency range 270-470/470-670 MHz • Input level -20 dBm to -10 dBm • Frequency stability 10Е-6 • Out-band suppression > 60 dB • Compatible Modulation Schemes QPSK, 64/256QAM, COFDM, AM, FM • IF Input impedance and connector 75 Ohm, F- type female  • RF Output impedance and connector 50 Ohm, N- type female • RF Monitoring Output 50 Ohm, N type female • Operating temperature range -35...+40° С • Relative Humidity 100% • Power Consumption 60/300/500 VA • Cooling forced air, temperature control • Injector Powering 220 VAС • Transmitter Powering 48 VDC • Transmitter dimensions 600х600х320 мм • Power module dimensions Rack 3U Transmitter MMDS  Аntenna : The MMDS antenna is intended for use in the MMDS and WI-FI systems. The antennas are available in various models. The antenna radiation pattern in horizontal plane can be circular or sector. The radiation pattern in vertical plane can be of 3 or 6 degrees depending on antenna gain. The antenna polarization is vertical or horizontal. Technical parameters: • Gain 10/13 dB • H. plane beamwidth 120/240/360 degrees • E. plane beamwidth 3/6 degrees • Polarization linear (vertical or horizontal) • Radiation Pattern Flatness <1dB • Input impedance and connector 50 Om N type female • Length 1500/3000mm • Diameter 160mm  |
