GPS 分配器 ALDCBS1X4

产品名称：GPS 分配器 ALDCBS1X4 品牌：GPS Networking 型号：ALDCBS1X4 频率：1.1-1.7GHZ 阻抗：50Ω 增益：18.4dB 输入驻波比：2.0 输出驻波比：1.8 噪声系数：4.2dB 反向隔离度：0.5-1dB 幅度平衡：0.5dBMAX 相位平衡：1.0degmax 隔离度：10dBmin 直流电压.：3.6-15Vdc(Non-Network Configuration, DC Input on J1) 直流电流：15mA(Amplifier Current Draw, All ports - 50Ω) PI dB：-2.0dBm Electrical Specification, TA = 25oC 描述： The ALDCBS1X4 GPS Amplified Splitter is a one input, four output   with a 17dB minimum gain block. The frequency covers the GPS L1  & L2 bands with excellent gain flatness. In the normal configuration,  one of the splitter RF outputs (J1) passes DC from the connected GPS  receiver through the splitter to the antenna, allowing the GPS receiver to power both the antenna and the splitter’s amplifier. The other RF  outputs (J2, J3 and J4) are DC loaded with a 200Ω resistor to simulate  the antenna current draw and prevent false antenna fault  from  connected receivers
