Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61. This plas-tic is also 100% recyclable.Typical EMI Spacer Gasket Design ParametersThe EMI spacer gasket concept can be considered using the design parameters shown in Table 2.

This unit specializes in elastomer finite element analysis (FEA) using MARC K6 series software as a foundation for FEA capability.Benefits of FEA include:•Quickly optimizing elastomer gasket designs•Allowing accurate predictions of alternate elastomer design concepts •Eliminating extensive trial and error prototype evaluationTypical use of FEA in EMI spacer gasket designs is to evaluate the force vs. deflection requirements of alternate designs.For example, onespacer design features a continuous bead of con-ductive elastomer molded onto a plastic spacer. An alternative designemploys an “interrupted bead,” where the interrup-tions (gaps left on the plastic frame) are sized to maintain the requiredlevel of EMI shielding. Figure 4illustrates these alternative designs.Gasket DeflectionFigure 5 compares the effect of continuous and interrupted elastomer gasket designs in terms of the force required to deflect the conductive elastomer. This actual cellular handset application required a spacer gasket with interrupted bead to meet desired deflection forces.Chomerics Designand Application ServicesChomerics will custom design a spacer for your application.

GM388电台咪接头定义及电台编程适配器研制

GM388电台咪街头定义及电台编程适配器研制GM388电台是美国Motorola公司生产的一种专业级无线电通讯设备,它采用了当今先进的计算机技术及数字锁相环频率合成技术,目前广泛用于我国地震勘探通信领域。
该电台的调试方法和其它类型的电台相比,有着很大的区别。
它要通过GM338电台编程适配器,把GM338电台和PC机连接起来,再使用专用调试软件,才能实现对GM338电台技术指标的调试及编程。
随GM338电台配备的编程适配器不能满足GM338电台维护及检修需要,为了满足生产需求,适合GM338电台的编程适配器,本文对此进行了详细地介绍。
1 PC机串口通信的基本原理PC机串行端口使用的是RS232C,其基本作用是进行CPU和串行设备间的编码转换。
当数据从CPU经过串行端口发送出去时,字节数据转换为串行的位数据;在接收数据时,串行的位数据被转换为字节数据。
RS232C采用负逻辑规定逻辑电平,电平信号与通常的TTL电平信号也不兼容。
RS232C将-5~-15V规定为“1”,+5~+15V规定为“0”。
而GM338的逻辑电平信号是TTL电平信号(逻辑1为+5V,逻辑0为0V),因此,RS232C驱动器与TTL电平信号连接时必须进行电平信号转换。
RS232C接口定义及连线:标准指出,DTE应该拥有一个插头(针输出),DCE拥有一个插座(孔输出)。
RS232C接口引脚定义:一个PC机完整的RS232C接口有22根线,采用标准的25芯插头(或者9芯插头)。
25芯插头和9芯插头的主要信号线相同。
(1)主要信号线定义RS232C接口引脚定义见表1所列。
(2)电气特性RS-232C接口的数据传输速率最大可达到20kb/s, 虽然其传输距离只有15m。
但一般主机和单片机的串口通讯速率大多都在9600b/s,所以RS232C接口可以满足通讯需求。
(3)接口的典型应用大多数计算机系统与终端单元之间只需使用少量几根信号线连接即可工作,见图1所示。
关于车载电台的选购

关于车载电台的选购一、车载电台的选购原则:1、车载电台的特点:关于车载电台与手台的区别以及车载电台的分类,我们将在另外的帖子里详细讨论。
在此,我们只简述一下适合我们车腿使用的车台的特点:A、功率大,通联距离远。
目前市场上适合我们车腿使用的车台在70厘米波段的发射功率一般在25-50W之间,比手台要大很多倍,通联范围也相应增大很多。
B、功能强大,技术指标好,坚固耐用。
一般车台都具有很多的实用功能,使用上方便灵活。
同时他们的技术指标和质量也高于一般手台(主要指国产手台),使用寿命很长。
C、固定安装,可以在车辆、家庭和办公场所使用。
车载电台不便于随身携带使用,适于在车辆和房间内固定安装使用。
D、需要大功率专业电源供电。
车载电台一般需要专业通讯电源提供13.8V的直流电,供电电流一般应大于20A。
在车内安装时可以直接接在12V汽车电平上使用。
E、车载电台自身不配备天线,但可以接驳任何类型的天线。
F、双段和多段车载电台一般具有很宽的接收范围和双段/多段发射能力,可以监听许多频段。
同时他们中大多数还具有双监听/双显示功能。
G、新一代的车载电台一般都具有机身/面板分离功能,可以方便地在车内任何地方安装、使用。
2、我们车腿的一般选购原则:A、具有业余无线电爱好者可以使用的收发频率范围。
比如,单段车台要能够在430-440MHZ的频率范围内收发。
当然如果是双段车台要可以在U/V段具有收发功能。
B、接收灵敏度好。
C、操作简便、使用灵活。
可以手制频。
D、适合的发射功率,一般在25W以上。
E、在较高的性价比范围内,具有尽量多的使用功能和好的应用口碑。
F、最好支持上中继、亚音、差转功能。

GM8387C:48 位双像素 LDI 发送器
产品概述
GM8387C 型 48 位双像素 LDI 发送器实现的功能是将 24 位(单像素工作模式)或 48 位(双像素工作模式)的并 行数据转换为 4 对或 8 对 LVDS 串行信号,同时并行输出 1 路 或 2 路 LVDS 时 钟 信 号 。 输 入 参 考 时 钟 频 率 范 围 32.5MHz~112MHz。 GM8387C 可支持在主机和平板显示器之间 QXGA 型 图象的传输;控制信号 Vsync、Hsync、DE 和两个用户定 义信号在消隐区间时传输。 GM8387C 具有单像素、双像素和单像素-双像素三种 工作模式,具有预加重和直流平衡编码功能。 单像素模式下, 芯片将输入的 48 位信号的低 24 位进行 读入编码, 输出 4 对 LVDS 数据信号和 1 路 LVDS 时钟信号, 其余通道为高阻态。双像素模式下,芯片将输入的 48 位信 号编码,输出 8 对 LVDS 数据信号和 2 路 LVDS 时钟信号。 单像素-双像素模式下, 芯片将输入的 48 位信号的取其低 24
