L-band Dual System Full Rack Integrated Switching Solution Features 950 - 2050 MHz (L-band) Solid State Transmitter and Receiver Racks: 12 Inputs by 48 Outputs (Fan-Out modules) 48 Inputs by 12 Outputs (Fan-In modules) Local Control : Graphical LCD Touch Screen Remote Control: RS-485 Model L-band Dual System Subsystem # Power Supply Module # 12x 12 Fan-In Module # 12x12 Fan-Out Module # Slave Control Module # Master Control Module # Signal Attenuation Control Module Description The L-band Dual System is composed of two Full Duplex Transmitter (Tx) and Receiver (Rx) racks; operating from 900 to 2050 MHz. This L-band Teleport is unique such that the system has a single Master Control Module (located on the Rx rack), while the Tx rack is controlled via a Slave Control Module. Thus, when closing a path on the receiver side, a matching path will also be closed on the transmitter end. This sophisticated switching system is built by cascading (4) 12x12 Fan-Out and (4) 12x12 Fan-In Modules to create 12x48 configuration on the Rx rack respective 48x12 configuration on the Tx rack. On the Rx rack, all (4) 12x12 modules are routed to a Master Control Module and integrated to a 12x48 system, while on the Tx rack it goes to the Slave Control Module. The system is fully controlled through Master Controller Module (from Rx rack), which is equipped with Windows 2000 Professional operating system (CPU), graphical LCD touch screen display and a removable hard disk. On the rear panel, 12x12 Modules Fan-out modules are interconnected using 9-pin CANbus D-connector. The L-band system is also loaded with (4) Fiber Optic Modules; two for transmitting and two for receiving signals. In addition, each rack is equipped with a Power Supply module, a Signal Monitor panel, and a Signal Attenuation Control module. Furthermore, the Rx rack is populated with (6) L-band amplifiers. v2.1 10/09 Photo: L-band Dual System Control Interfaces Local Control: LCD Touch Screen Display 6.4" VGA TFT LCD Operating System Microsoft® Windows® 2000 Professional Low power CPU (on board) VIA Eden EP6000 (667 MHz) EBGA Memory 128 MB Removable Hard Drive 20 GB External USB port For mouse or keypad control Remote Control: RS-485 9-pin 'D' sub-miniature female connector Environment Operating Temperature: Storage Temperature: Operating Humidity: Storage Humidity 0 °C to +50 °C -25 °C to +50 °C 70% (non-condensing) 70% (non-condensing) www.dowkey.com [email protected] L-Band Dual System Full Rack Integrated Switching Solution RECEIVER RACK: TRANSMITTER RACK: RF Characteristics A-2 A3-1 A-2 Impedance 50 Ohms Operating Frequency 900 - 2050 MHz VSWR (max) 1.8:1 (Input) 1.8:1 (Output) A3-2 Isolation (min) 55 dB input / input A3-3 A3-4 A3-6 A-4 A-5 A-6 A3-3 55 dB output / output (Different Input) A3-4 Gain (any path) 0 +/- 2.5 dB Noise Figure 12x48 modules (max) 17 dB Noise Figure 48x12 modules (max) 21 dB 1 dB Compression Point (min) +10 dBm (Output) 3rd Order Intercept Point (IP3) min. +21 dBm (Output) Physical A-7 . . .
