HIGH POWER CHANNEL SELECTIVE SMR/iDEN/TDMA REPEATER MAIN FEATURES • 50 Watt 1dB Output Power • 10 Watt Downlink Composite Power • 90 dB RF Gain • Flexible Software Controlled Filter Array • 1 to 8 Programmable Filters, 1 to 8 Channels each Filter • Separate Programmable Bandwidth for each Channel • High Spectral Purity • Small Dimensions • Exceptionally linear operation • Computer (Laptop) Control and monitor • Output Power & Fault Monitor • Special Tailoring Capability to meet Specific Customer Requirements • Patent Pending Dekolink’s new Digital Channel Selective Repeater employs advanced Digital Signal Processing technology (DSP) that provides significant advantages over conventional repeaters. This innovative system introduces new system capabilities, which enable a wide variety of applications particularly when adjacent channel selectivity and very high spectral purity and selectivity is required. The Digital Channel Selective Repeater generates a flexible array of 8 DSP based software controlled independent variable bandwidth channels across the whole 800 MHz SMR band. Each channel parameters such as central frequency, bandwidth, and filter slopes, are all software controlled in a local mode and can be remotely controlled via a wireless modem. The 800 MHz SMR band is crowded with many different services. Services such as IDEN, LMR, SMR and Public Safety are interfering with each other in the same geographical area making it often impossible to support these services simultaneously. The Digital Channel Selective Repeater provides a very efficient solution to the 800MHz interference problem by enabling high spectral selectivity while maintaining a clear low noise spectrum. The Digital Channel Selective Repeater has a built-in software controlled frequency shift capability making this product ideal for those applications where frequency shifting is required and particularly in sites where high gain is required under poor antenna isolation conditions. Dekolink’s Digital Channel Selective Repeater provides a 40dbm composite output power, ideal for outdoor applications. Dekolink also provides a cost effective medium power system providing the same features and capabilities but with 32 dBm composite power. These amplifiers are an excellent choice for in-building coverage applications when frequency selectivity is required. Dekolink Wireless Proprietary and Confidential Information.
