RBS2101~RBS2103系列这种设备属于室外安装类型的设备，那个类型的基站设备重要为室外的情形应用而设计的，除了主设备以外，还有空调，温度操纵，供电等从属设备，平日采取自力供电进行工作，能够防雨水、防霜冻等。
但受外界干扰较大年夜，晦气收集的稳固。
在我国GSM运营商几乎不应用该系列的机型。
RBS2202系列这种类型的设备属于室内安装的设备，构造较RBS2100系列的设备简单，没有自力的外部情形体系，弗成自力供电（但能够自带整流模块）等，必须在室内安装应用。
这种系列是我国GSM运营商所采取的重要Ericsson设备类型。
RBS2301、RBS2302、RBS2402、MAXITE系列这种类型的设备属微蜂窝设备，能够在室内和户外安装，能够自力供电应用，体积较小，安装灵活便利。
重要用在街道覆盖、室内覆盖等。
RBS2206系列这种类型的设备属于室内安装的设备。
RBS2206 是一种室内型宏蜂窝基站设备，每个机柜可支撑最多12 个收发信机。
其机柜与RBS2202 占地面积雷同，略高，因为采取新型两倍容量的收发信机和合路器，机柜的载波容量也是RBS2202 的两倍。
其“双收发信机”—dTRU—与今朝的单个TRU 体积雷同，却在一个单位里包含有两个收发信机2、RBS2000系列基站构成：下图是RBS2000在收集中的地位及构造：●移动台（MS）：移动用户应用的便携终端。
由收发信机、天线、人机介面、电池等构成；●基站（BS）：基站收发信机、操纵设备、天馈体系等构成，供给MS与BSC●基站操纵器（BSC）：为MSC接口，治理BS。
移动交换中间（MSC）：收集的核心，供给交换、收集操纵与治理、互连接口等功能。

Tolerance and Type Number Designation. The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%.2. ZENER VOLTAGE (Vz) MEASUREMENT - guarantees the zener voltage when measured at 40 ms +- 10ms from the diode body, and an ambient temperature of 25 °C (+8°C , -2°C ).3.ZENER IMPEDANCE (Zz) DERIVATION - The zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having an rms falue equal to 10% of the dc zener current (I ZT or I ZK ) is superimposed on I ZT or I ZK .4. SURGE CURRENT (Ir) NON-REPETITIVE - The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I ZT , per JEDEC standards, however, actual device capability is as described in Figure 3.ELECTRICAL CHARACTERISTICS(T A =25°C unless otherwise noted) (V F =1.2Volts Max, I F =500mA for all types.)Device (Note 1.)Nominal ZenerVoltage V Z @ I ZT(Note 2.)Test current I ZTMaximum Zener Impedance(Note 3.)Leakage Current SurgeCurrent@T A =25°C(Note 4.)Z ZT @ I ZT Z ZK @ I ZKI RRating and Characteristic Curves (CZRB3011Thru CZRB3100)Fig.2-TYPICAL THERMAL RESPONSE L,P.W.PULSE WIDTH (ms)0.10.050.030.020.010.0050.0030.0020.0010.00050.00030.00020.0001NOMINAL VZ (VOLTS)Fig.3-MAXIMUM SURGE POWERFig.4-TYPICAL REVERSE LEAKAGEVZ,ZENER VOLTAGE @IZT (VOLTS)VZ,ZENER VOLTAGE @IZT (VOLTS)Fig.5-UNITS TO 12VOLTS Fig.6-UNITS 10TO 100VOLTSRating and Characteristic Curves (CZRB3011 Thru CZRB3100)VZ,ZENER VOLTAGE (VOLTS)VZ,ZENER VOLTAGE (VOLTS)L,LEAD LENGTH TO HEAT SINK(INCH)TYPICAL THERMAL RESISTANCEAPPLICATION NOTE:Since the actual voltage available from a given zener diode is temperature dependent, it is necessary to determine junction temperature under any set of operating conditions in order to calculate its value. The following procedure is recommended:Lead Temperature, T L, should be determined from:T L = șLA P D + T AșLA is the lead-to-ambient thermal resistance (°C/W)and PD is the power dissipation. The value forșLA willvary and depends on the device mounting method.șLA is generally 30-40 °C/W for the various chips andtie points in common use and for printed circuit boardwiring.The temperature of the lead can also be measured using a thermocouple placed on the lead as close as possible to the tie point. The thermal mass connected to the tie point is normally large enough so that it will not significantly respond to heat surges generated in the diode as a result of pulsed operation once steady-state conditions are achieved. Using the measured value of T L, the junction temperature may be determined by:T J = T L + ¨T JL ¨T JL is the increase in junction temperature above the lead temperature and may be found from Figure 2 for a train of power pulses or from Figure 10 for dc power.¨T JL = șLA P DFor worst-case design, using expected limits of Iz, limits of PD and the extremes of TJ (¨T JL ) may be estimated. Changes in voltage, Vz, can then be found from:¨V = șVZ¨T JșVZ , the zener voltage temperature coefficient, isfound from Figures 5 and 6.Under high power-pulse operation, the zener voltagewill vary with time and may also be affected significantly be the zener resistance. For best regulation, keep current excursions as low as possible.Data of Figure 2 should not be used to compute surge capability. Surge limitations are given in Figure 3. They are lower than would be expected by considering only junction temperature, as current crowding effects cause temperatures to be extremely high in small spots resulting in device degradation should the limits of Figure 3 beexceeded.COMCHIPSurface Mount Zener Diode。
