ESA E4402B，1GC1-4210有缺陷

你好tabbott，谢谢！
无论如何我会尝试



以下为原文

Hello tabbott and thanks!

I will try anyway

嗨，我和我的e4403b有类似的问题，它是一个4x预分频器（我用Hittite预分频器替换它），我认为e4402和e4403有相同的主板，我有关于我的e4403b的CLIP信息
。
如果您愿意，我可以检查原理图并告诉您真正的组件名称



以下为原文

hi,
i've had a similar problem with my e4403b, it was a 4x prescaler (i replace it with an Hittite prescaler), i think that the e4402 and e4403 have the same board, and i've the CLIP information about my e4403b.
If you want i can check the schematics and tell you the true component name

嗨，我有同样的问题LO UNLOCK，我认为问题是4x preescaler。
你能检查原理图并告诉我真正的组件名称。
我等待你的回复谢谢

hi, i´ve the same problem LO UNLOCK, i think the problem is 4x preescaler.

Could you check the schematics and tell me the true component name.

I await your response

Thanks

我正在添加这个旧线程，以添加一些信息，这可能有助于其他人寻找修复他们的E4302 / 3/4/5/7/8 SA。
关于维修E4307B的uTube视频似乎已经引起了很多兴奋，并且在eBay上破坏了E430x系列SA的价格，但是为了我自己的用途已经购买了几个，结果发现在那个uTube视频中使用的CLIP
并且只能与旧单元匹配，即使是那个我也无法找到带有RF底板布局和原理图的干净副本的版本，您可以阅读文本。
自那个版本和单元I具有非常不同的电路并且不使用相同的设备时，已经对RF / LO板进行了多次修改。
我使用的是Agilent 1GC1-4210“多模数分频器”，Keysight不再为这些装置（16针塑料）提供正确的封装。
还有一些芯片剩余房屋的价格从100美元到几百美元不等。
有关裸片的数据表可在Keysight网站上找到（但不是表面贴装塑料封装的引出线），但我一直无法找到合适的，更便宜的替代品。
同样，经过几个小时的搜索，我一直无法找到更新的CLIP原理图，这些后来的电路板。
我的4203B主板是E4203-60100，另一个是E4203-60107。
希望有些人会发现上述信息有用。
由于是德科技似乎没有兴趣使更新的CLIP可用（或者甚至是旧的CLIP可用），如果有人能够至少制作一些好的RF板顶部，那么对我们中的许多人来说非常有帮助。
底部布局和原理图并将它们发布在Yahoo网站上。
同样，如果有人知道1GC1-4210的替代品更便宜，而且可能仍然是生产产品，这将使我们中的一些人非常感激。
谢谢阅读，
罗恩

I'm adding to this old thread to add some info that may be helpful to other looking to repair their E4302/3/4/5/7/8 SA. The uTube video on repairing an E4307B seems to have generated a lot of excitement and has driven up prices on broken E430x series SA's on eBay but having bought a couple of them for my own use, it turns out that the CLIP used in that uTube video and available only matches older units and even that one I've been unable to find a version with a clean copy of the RF bottom board layout and schematic that you can read the text. There have been several revisions of the RF/LO board since that version and the units I have very different circuity and do not use the same devices. Both units I have use an Agilent 1GC1-4210 "Multi-modulus Divider" which Keysight no longer makes available in the correct package for these units (16-pin plastic). There are still some chip surplus houses that have them ranging from about $100 to several hundred dollars. The data sheet for the bare die is available on the Keysight website (but not the pinout for the surface mount plastic package) but I've been unable to find a suitable, less expensive replacement. As well, after hours of searching, I've been unable to find a more current CLIP with schematics for these later boards. My 4203B board is E4203-60100 and another I have is E4203-60107.

Hopefully, some will find the above information useful. Since Keysight appears to have no interest in making the more current CLIP available (or even the old one that's in general circulation), it would be very helpful to many of us if someone could at least make some good copy of the RF board top and bottom layouts and schematics and post them perhaps on the Yahoo site. As well, if someone knows of a replacement for the 1GC1-4210 that's less expensive and maybe a still in production product that would make some of us very grateful as well.

Thanks for reading,
Ron
