CDM625 ACM白皮书
CDM625中的ACM（自适应编码调制）技术及应用Comtech EF Data2009年6月1.概述自适应编码调制（ACM）是SCPC卫星MODEM‐625的一项最新功能，该功能需要MODEM配备最新的软件（1.4.0以上）、带有VersaFEC TM模块和FAST选项。
VersaFEC ACM是由Comtech EF Data 和Comtech AHA 公司开发和拥有的专利技术。
1)ACM将雨衰余量转化为更高的链路传输能力：与传统的CCM（固定编码调制）卫星SCPC链路相比，能够将链路速率提高一倍或更多。
这是通过自动调整FEC码率和调制方式来实现的。
2)无论链路状况如何（有噪声或其他干扰、晴天、降雨等），ACM总能使链路得到最大吞吐率。
ACM的初始设置很简单，之后由MODEM自动根据链路状况调整调制方式和FEC码率，再也不需要其他操作了。
3)使用CCM系统，严重的雨衰会导致链路中断，用户数据的吞吐率变为0；ACM则始终保持链路的连通性（降低速率），从而能显著提高系统的可用度。
4)CDM‐625中的ACM需要VersaFEC的支持，目前只能支持IP业务的传输。
（不使用ACM时，可以使用其他所有数据接口）。
2.背景ACM不是一个新的概念，已经在无线通信领域（包括地面微波通信）应用多年，只是近来才引入到卫星传输领域。
ACM的主要功能是：根据链路的信噪比状况自动调整调制方式和FEC码率，来优化无线链路的吞吐率。
应当注意的是：改变调制方式和FEC码率，会直接影响频谱效率（bps/Hz）。
这个概念有一个隐含条件：无线通信系统的符号速率（sps）和发射功率必须维持恒定，这样才能保证一个特定的链路永远也不会超过所分配的带宽。
所以，ACM工作时，需要保持符号速率恒定，而业务数据速率动态改变。
请看一下这个简单的公式：R S = R i / ( Mod * FEC )例如：QPSK调制（Mod = 2）， ¾，这个公式就变为：R S = R i * 0.666从上述公式可以推导出：R i = R S * Mod * FEC所以，当采用更高阶调制或更高FEC码率时，链路的比特速率Ri就增加；当采用低阶调制或更低FEC码率时，链路的比特速率Ri就减少。

机械特性
625合金的强度源于镍铬合金中 所含的钼、铌固溶体强化效应。这 些元素也使该合金具有卓越的耐腐 蚀特性。虽然该合金是为适应高温 环境的强度而设计的,其高度合金 组合使其具有对一般腐蚀的高度耐 受能力以及对广泛氧化和非氧化环 境的耐受能力。铬、钼含量使合金 具有抗氯化物离子产生的蚀损斑的 优良特性,高镍含量增强合金对氯 化物应力腐蚀裂化的抵抗能力。

Nickel 141 焊条Nickel 141 焊条主要用于Nickel 200、Nickel 201合金的药皮焊条电弧焊，和镀镍钢材在镀镍层一侧的焊接，也可用于钢的堆焊。
焊缝金属中钛和碳产生反应使游离态的碳降到比较低的水平，因此这种焊条可以用于低碳镍合金（Nickel 201）的焊接。
焊缝金属具有优异的耐蚀性能，特别是耐碱金属腐蚀的能力。
这种焊条也可用于异种材料的焊接，包括Nickel 200合金和Nickel 201合金之间的焊接以及各种铁基和镍基合金的焊接。
Nickel 141 焊条适用于全位置焊接。

这种金属可抵抗海水，盐类以及还原酸性物质的侵蚀。
用这种焊条形成的焊缝能满足苛刻的X射线照相探伤要求。
需要说明的是，虽然用这种焊条焊接MONEL K-500合金可形成性能优异的接头，但与母材不同的是，焊缝填充金属不能产生时效硬化效果，所以相对强度较低。

Inconel625什么牌号Inconel625材料性能
5.乙酸和乙酐反应发生器6.硫酸冷凝器时效处理对合金力学性能的影响图7为不同温度、时间的时效处理对GH3625合金强度和塑性的影响。
从图76)看出，时效处理后合金的抗拉强度均不同程度的提高，但是600℃的抗拉强度明显高于其他两个温度时效后的抗拉强度·这是因为600℃时效不同时间后·合金的微观组织未发生明显变化，文献De也指出：In e one l 625合金在600℃长期时效后合金的微观组织不会发生明显变化，而当温度高于600℃后，合金会析出不同的碳化物、y"相和8相，从而对合金性能产生一定的影响。
值得注意的是，800℃时效30h和60h后合金的抗拉强度均低于初始状态下的抗拉强度，随着时效时间的进一步延长·抗拉强度进一步提高，这是因为时效前期·晶界处析出大量富Cr、Mo、Nb元素的M，，C，型碳化物和富Cr、Mo元素的M.C型碳化物，从而基体中起固溶强化作用的合金元素相对减少，弱化了固溶强化效应，而GH3625合金本身又是一种以Mo、Nb元素起强化作用的固溶强化型合金·因此合金经800℃时效30h和60h后合金的抗拉强度均低于初始状态下的抗拉强度；当时效时间维续增加到90h后，基体中还析出了针片状的8相，由于8相与y基体具有非共格关系，因而能够起到一定的弥散强化作用28，针状8相的周围区域存在位错缠绕，导致位错运动受阻从而提高晶界强度·因此合金的抗拉强度逐渐上升。
对于GH3625合金时效处理后屈服强度的变化而言：3种温度下时效处理后屈服强度的变化基本似，即时效初期·合金屈服强度明显升高·随着时效时间的延长·屈服强度基本未发生变化。
这是因为时效初期合金中析出了GH3625合金主要的强化相("相).y"相与y之间的点阵错配度大·y"/y界面的共格应力可产生显著的强化作用，从而产生很高的屈服强度34：28.从图76)中还可以看出800℃的屈服强度明显低于600℃和700C的屈服强度·这是由于在800℃时，有部分y"相已经转变成8相·减弱了y"相的强化效果：这与微观组织图像中观察到的结果一样。

Satellite Modems
Overview
The CDM-625 Advanced Satellite Modem builds on Comtech EF Data’s legacy of providing the most efficient satellite modems. It is the first modem to combine advanced Forward Error Correction (FEC) such as VersaFEC and Low Density Parity Check (LDPC) codes with the revolutionary DoubleTalk Carrier-inCarrier bandwidth compression, allowing for maximum savings under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to: Minimize operating expenses (OPEX) Maximize throughput without using additional transponder resources Maximize availability (margin) without using additional transponder resources Minimize capital expenses (CAPEX) by allowing a smaller BUC/HPA and/or antenna Or, a combination to meet specific business needs The advanced technologies and features of CDM-625 are covered by a number of U.S. patents including 7,254,188, 7,353,444, 7,415,659 and other pending patents.

Inconel625
Inconel625合金介绍以及应用INCONEL625是Ni-Cr基固溶强化变形高温合金，以铬、钼和铌为主要固溶强化元素，是最高使用温度可到950℃，该合金从低温到980℃均具有良好的抗拉强度和抗疲劳性能，且加工和焊接性能良好。
合金具有优良的耐腐蚀和抗氧化性能，并且耐盐雾气氛下的应力腐蚀。
广泛应用于制造航空发动机零件、宇航结构部件和化工设备。
主要产品有板材、棒材、丝材、管材、带材和锻件。
INCONEL625合金现在已广泛应用于制造航空和航天发动机机匣、导向叶片、安装边和筒体、燃油总管等零部件，INCONEL625合金无论在海洋气氛还是在非海洋气氛中，腐蚀速度都很小，抗海水腐蚀能力很好。
合金耐各种盐类溶液的腐蚀，具有良好的耐硝酸及磷酸腐蚀的能力。
对加热至沸点以下的盐酸和低溶度的硫酸腐蚀也有相当的抗力。
合金在550℃~700℃长期使用后有一定的时效硬化现象，可导致合金塑性有一些下降。
美标牌号：Inconel625（UNS N06625）、中国牌号：GH3625（GH625）、法国牌号：NC22DNb。
Inconel625执行标准：Inconel 625 的化学成分:合金强化固溶强化加入与基体金属原子尺寸不同的元素(铬、钨、钼等)引起基体金属点阵的畸变，加入能降低合金基体堆垛层错能的元素(如钴)和加入能减缓基体元素扩散速率的元素(钨、钼等)，以强化基体。
沉淀强化通过时效处理，从过饱和固溶体中析出第二相(γ'、γ"、碳化物等)，以强化合金。
γ'相与基体相同，均为面心立方结构，点阵常数与基体相近，并与晶体共格，因此γ相在基体中能呈细小颗粒状均匀析出，阻碍位错运动，而产生显著的强化作用。
γ'相是A3B型金属间化合物，A代表镍、钴，B代表铝、钛、铌、钽、钒、钨，而铬、钼、铁既可为A又可为B。
镍基合金中典型的γ'相为Ni3(Al,Ti)。
γ'相的强化效应可通过以下途径得到加强:①增加γ'相的数量;②使γ'相与基体有适宜的错配度，以获得共格畸变的强化效应;③加入铌、钽等元素增大γ'相的反相畴界能，以提高其抵抗位错切割的能力;④加入钴、钨、钼等元素提高γ'相的强度。

Links:TMS320C6745TMS320C6747Device Configuration Copyright ©2008–2014,Texas Instruments Incorporated 4.3Pullup/Pulldown ResistorsProper board design should ensure that input pins to the device always be at a valid logic level and not floating.This may be achieved via pullup/pulldown resistors.The device features internal pullup (IPU)and internal pulldown (IPD)resistors on most pins to eliminate the need,unless otherwise noted,for external pullup/pulldown resistors.An external pullup/pulldown resistor needs to be used in the following situations:•Boot and Configuration Pins:If the pin is both routed out and 3-stated (not driven),an external pullup/pulldown resistor is strongly recommended,even if the IPU/IPD matches the desired value/state.•Other Input Pins:If the IPU/IPD does not match the desired value/state,use an external pullup/pulldown resistor to pull the signal to the opposite rail.For the boot and configuration pins,if they are both routed out and 3-stated (not driven),it is strongly recommended that an external pullup/pulldown resistor be implemented.Although,internal pullup/pulldown resistors exist on these pins and they may match the desired configuration value,providing external connectivity can help ensure that valid logic levels are latched on these device boot and configuration pins.In addition,applying external pullup/pulldown resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in switching operating modes.Tips for choosing an external pullup/pulldown resistor:•Consider the total amount of current that may pass through the pullup or pulldown resistor.Make sure to include the leakage currents of all the devices connected to the net,as well as any internal pullup or pulldown resistors.•Decide a target value for the net.For a pulldown resistor,this should be below the lowest V IL level of all inputs connected to the net.For a pullup resistor,this should be above the highest V IH level of all inputs on the net.A reasonable choice would be to target the V OL or V OH levels for the logic family of the limiting device;which,by definition,have margin to the V IL and V IH levels.•Select a pullup/pulldown resistor with the largest possible value;but,which can still ensure that the net will reach the target pulled value when maximum current from all devices on the net is flowing through the resistor.The current to be considered includes leakage current plus,any other internal and external pullup/pulldown resistors on the net.•For bidirectional nets,there is an additional consideration which sets a lower limit on the resistance value of the external resistor.Verify that the resistance is small enough that the weakest output buffer can drive the net to the opposite logic level (including margin).•Remember to include tolerances when selecting the resistor value.•For pullup resistors,also remember to include tolerances on the IO supply rail.•For most systems,a 1-k Ωresistor can be used to oppose the IPU/IPD while meeting the above ers should confirm this resistor value is correct for their specific application.•For most systems,a 20-k Ωresistor can be used to compliment the IPU/IPD on the boot and configuration pins while meeting the above ers should confirm this resistor value is correct for their specific application.•For more detailed information on input current (I I ),and the low-/high-level input voltages (V IL and V IH )for the device,see Section 5.3,Recommended Operating Conditions.•For the internal pullup/pulldown resistors for all device pins,see the peripheral/system-specific terminal functions table.。
