RF Switches Forum Discussions
Hi Infineon team.
Please help to confirm the following information as soon as possible for the BGS13SN8E6327XTSA1 switch, which has been tested and found to be
1. If pin VDD/V1/V2 are not powered up, all pins are high resistance to ground.
2. In the case of power-on test, the selected pin is found to be high resistance to ground, while the other twopins become low resistance to ground (short circuit).
For example, when V1/V2 is 1/0, RFin connects to RF1, RF1 has high resistance to ground, and RF2/RF3 have low resistance to ground, with a resistance value of about 4ohm.
Please help confirm the following questions:
1. Are the above test results correct?
2. If the above test results are correct, why should the 2pins that are not selected during power-up be shorted to ground, and for what reason? Is this the case for all RF switches, or is this the only device designed this way? In many analog switches, all pins are in a high resistance state to ground at power up, whether they are selected or not.
3. Is there any device with similar function that is still high resistance to ground even if the pin is not energized at power-up?

Show LessHi,
For a specific design, I need to know exactly what is the capacitance of RFc port.
1. When connecting to RFx port
2. When open
Does anyone have this information ?
Thanks
Show LessWe have a problem with the switches. When measuring in the DVB-C range the switch always loses 1 db MER. With 4 switches it adds up to 4 db MER. The MER should be 40 db, but it is 36 db at the output. We previously had relays inside and these did not cause any problems. The level is fine. We have no problems in the SAT range.
Show LessHello,
is there a limit to the number of cycles I can reflow solder the BGS14M8U9?
We place our components in a two stage workflow with the BGS14M8U9 being the first component in the PCB. Can it endure another solder cycle or does this have any impact on the product?
Best regards
Show LessHello,
Is it possible to connect two BGS18MA12 on the same MIPI bus?
If it rewrites the USID to the individual ID then it seems to be possible but I don't know if it is possible or not.

Hi,
I want to use this switch to conmute between NBIoT and WMBUS (868MHz) technology.
But I dont see the recomendations of the digital lines and another details of the layout of this switch.
Can you provide it?
Best regards
Show LessBGS12WN6を採用するうえで、設計上の参考にしたいので、評価ボードの資料等ございますでしょうか?
Webを拝見させて頂き、Eagleファイルはダウンロードしましたが、ICのライブラリデータしか入っていませんでした。
さらに、Eval Board User Guides資料も確認しましたが、基板構成(レイアウト)は記載されているのですが、評価ボードのパターン形状が分かりませんでした。
何か評価ボードのパターン形状が分かる資料ありましたら、頂くこと可能でしょうか?
