你好对话框，
I incorporated your PCB antenna design to make a circuit like the one that you have on your QFN48 module described in document UM-B-036. However, my PCB manufacturer cannot make copper as thin as .018mm and the smallest that can be done is .035mm. Will the antenna's performance be significantly degraded with a thicker antenna?
谢谢，

嗨svl0822，
它的属性不会产生大量变化，但实际上会发生一些不匹配和迷失。
The effective length of the antenna will be about 2% less, and it's impedance also will decrease by the same amount I believe.
通过施加和调整天线匹配网络，可以补偿该变化。不确定这是值得的麻烦。
您的设计周围的外壳会对天线性能产生更多影响。

嗨bb_dialog，
My manufacturer told me that, there is not NC drill layer. So they cannot product it.
Could you kindly send me the gerber files about PCB trace antenna reference design?
aaron.xu@ohtcom.com
问候，

Hi ohtcom,
您可以在跟踪天线PCB中的“参考设计”选项卡中找到PCB Trace天线REF DES。

谢谢mt_dialog.
你好，
我正在寻找一个具有良好性能和尺寸小的天线解决方案。
在那里我看看参考设计如下：
- Proximity Tag.
- Battery Powered Beacon both has PCB trace antenna (Similar to MIFA)
我想知道，这个参考设计中的哪一个具有更好的天线性能，因此我可以遵循相应的参考设计？
It would be great if you can provide some test report of the same.
嗨bimalsinh，
关于参考设计中使用的印刷站的性能的信息可以在AN-B-027文档中找到，在该文件中检查和评估文档不同的天线实现，对每个天线附加有关回波损耗和辐射模式的测量在文档上引用。
谢谢mt_dialog.
Hi MT_dialog.
感谢您的快速支持，它将有助于我们在天线设计。
除此之外，您可以在下面查询时帮助我：
- I want to have to DA14583 Dev kit schematic design files for reference, Can you please provide the same?
- As we want to measure 2 seperate battery(CR2032) voltage level, Where one will be measured through internal VBAT3 battery level measurement. for another we require to connect Vbat to ADC IN with resistor devider. Can you please confirm the Internal ADC reference will be at 1.2V?
- DA14583是否支持撤销或电压监控器？在VBAT低于阈值时保持复位状态以重置状态。
寻找快速支持。
嗨bimalsinh，
您将能够找到583 Duaghterboard的所有可用原理图，如果您选择的产品链接14583选项，然后导航到亚博电竞菠菜
开发套件选项卡，选择Pro或基本套件，并在页面底部找到板的示例性，Gerbers，BOM和Blayout文件。
是的，数据表中定义的ADC引用是1.2V，X3衰减器达到3.6V。
不，58x系列不配备电压监控器的衰退检测。
谢谢mt_dialog.
嗨MT，
Thanks for your continuous support,
As mentioned it has internal ADC ref=1.2V with attenuatorx3,
- 是否可以将CR2032（3V）Dirrectly连接到ADC输入引脚以测量电池电量，而无需任何外部电阻驱动器（并且为该ADC输入引脚启用3X衰减器）？是否有任何特定引脚，或者可以从p0 [0-3]中选择它？
- In datasheet it mentions, DA14583 cold bootup should be avoided if Vbat<2.5V. Does that mean below Vbat <2.5V, SoC will not be functional?
- 对于VBAT <2.5V，它是否意味着SOC不应从OTP或内部闪存重新启动？
- 如DA14580中所述，它有一些问题是“使用P1-2，P1-3引脚作为切换此GPIO在RF性能中增加，因此DA14583中需要任何此类预防措施，或者此问题在此处得到解决？
嗨bimalsinh，
你不需要使用任何端口/针在订货单r to measure the battery voltage, the 58x has additional channels for measuring internal voltages and the battery voltage, if you take a look at the peripheral_examples in the SDK you will find an example that measures the battery voltage and uses the internal channels for this, or you can have a look in the datasheet and check the GP_ADC_CTRL_REG and the GP_ADC_SEL field.
-Regarding在VBAT <2.5V时运行，设备将工作，但这是对话保证的电压阈值，即设备将在没有任何问题的情况下运行。
- 我不明白这个问题，请澄清一下。
-Yes the same precaution stands for the 583 as well for pins P1_2 and P1_3 since its available only in QFN package.
谢谢mt_dialog.
嗨MT，
再次谢谢你的支持，
- 我确实理解DA1458X可以测量没有任何外部引脚输入（连接）的电池电压。但在我们的应用中，我有两个电池如下所示：
1）一个电池CR2032将为DA14583 SOC供电，用于测量此电池电量，我可以使用该内部ADC功能。
2) Second CR2032 will be powering external application circuit, To measure second battery voltage level, Do i need to have external resistor divider of 1.2V or is it possible to use internal 3Xattenuator? To achieve this is there any specific pin or can use any channel of ADC?
- 我们对VBAT <2.5V的关注，如下：
1）因此，根据您的建议，DA14583将以VBAT = 2.35V工作而不是VBAT = 2.5V。我得到它吗？
2) limitation of cold boot when VBAT<2.5V, Is this limitation applicable to only OTP memory or Internal Flash memory aswell?
3) We are not planning to use OTP memory of DA14583 (using only internal flash-1Mbit), Is there any issue applicable here at VBAT<2.5V?
- Is it ok to not use external Brownout Voltage supervisor IC, As DA1458x doesn't have it inbuilt? what may happen if i don't use Brownout IC? (We have replaceable Battery in product)
嗨MT，
在此等待您的快速回复，以最终确定BLE SOC选择。
嗨bimalsinh，
ADC的内部参考为1.2V，衰减器可达到约3.6V，因此如果电池高达3.6V，则可以使用内部衰减器。
Regarding the VBAT, as mentioned above the device operates as it should be in voltages over 2.5V regardless if the OTP is used by user or not (the 583 uses the OTP in
命令从OTP报头读取一些值，也可以镜像在OTP中刻录的583的引导加载程序。
是的，您可以使用外部监控器IC，如果使用，如果在更换电池等时电源导轨在电源轨道上或在电压下，则可以避免使用未定义状态。
谢谢mt_dialog.
嗨MT，
我想在简单的问题上有您的反馈意见：
电池测量：
- 测量电池电压时，目前ADC引脚的消耗量是多少？
- What is the current requirement for internal 3x attenuator? (Which will be power efficient internal 3x Attenuator or External resistor devidor?)
Power consumption:
- Is there any calculation sheet or way to find power consumption of DA14583 SoC? (Advertising Inteval:100msec, DataByte: 31 Byte)
嗨bimalsinh，
- The ADC has a typical supply current of 5uA at 100 ksamples regarding the current requirement (as mentioned in the datasheet) on the case with or without the attenuator the impedance of the ADC is infinite and with the attenuator is about 300K, so what is more efficient (with or without and with an external volatge divider) depends on your application.
- 不，没有功耗表，指示583以不同的广告间隔的功耗。
谢谢mt_dialog.
嗨MT，
在我的申请中，我想测量一定分钟的电池电压（15分钟）。我的信标广告是100毫秒。
我是否能够在扩展睡眠模式下放置SOC，并运行15分钟的计时器，之后它可以唤醒MCU并执行电池测量？
嗨bimalsinh，
Yes, you will be able to do so, you can trigger the ADC measurement via a ke_timer (app_easy_timer), the timers have a maximum time counting of about 5 minutes, so you can start a timer and every time the 5 minute timeout elapse set the timer again and count how many timer the timer has elapsed, on the 3rd time you can set the counter to zero and trigger the ADC measurement.
谢谢mt_dialog.
嗨MT，
Thanks for your prompt response,
因此，在My Timer运行时（5分钟）CPU将处于扩展睡眠模式。我理解是否正确？
另外一个问题，我没有找到使用特定主题添加新帖子的任何简单方法。你能引导我吗？
嗨bimalsinh，
The device when the sleep mode is enabled, it will sleep between the advertising events, when you set a ke_timer, essentially you program the device to wake up in the specified time in order to serve the callback that you ve set, so in the above implementation the device will sleep in between the advertising intervals (it needs to be awake in order to advertise) and it will wake up as soon as the timer that you ve elapses.
