PHS-Cell Site Amplifiers
Products Outline:AW1900A-7003J Series PHS Cell Site Amplifier, applied with the TDMA/TDD time division communication system, is specially designed for the purpose of effective PHS CS coverage. The equipment can absolutely replace the high-power PHS CS by cooperating with low-power PHS CS, which thus provides a low-cost and high-return method for the seamless PHS network construction.Ultra low noise amplifier employed in the uplinkSynchronous off/on control technology enables the cell site amplifier to transmit and receive in phase with the CS.High-linear power amplifier helps suppress spurious & IM3 the CS receiver sensitivity effectively.Product Features:Output power level is adjustable, and ALC technology can controlthe output power;Step-adjustable gain with great preciseness helps balance bothuplink and downlink;Full-bandwidth coverage; Adaptable to various types of CSs;Reduce the handover and the disconnection rate; improve speechquality;Optimized design facilitates the installation; Chassis qualifiesfor IP65;Reliability for GB6993-86; EMC qualifies for ETS300-609-4standard;Robust Operating & Monitoring function: the networkadministration center can keep track of system operations of allequipments both locally and remotely;Suitable for different situations, such as urban and suburbanareas, residential districts, mines, roads, railways, scenicspots, etc.Specifications:Frequency: 1895-1920MHzNumber of Channel: 8Max. Output Power Level (dBm): 30dBm, 33dBm,37dBmFrequency accuracy (Hz): ≤±0.05ppmGain: 23±2dBACPR: ≤-65dB@±600KHz, ≤-70dB@±900KHzNoise Figure: ≤2.5dBVSWR: ≤1.5Group Delay: ≤1µsSpurious:Intermodulation: ≤-36dBc/30KHzPower supply: AC220V±30%,45~55Hz
