Radio Frequency (RF) Forum Discussions

Hello everyone,

as for example the AS179-92LF, a SPDT switch up to 4 GHz, states that it is made of pHEMT GaAs FETs, there is no such information in the datasheet of the BGS14M8U9. Does anyone know if it is based on GaAs, GaN, Sic, FET or just MOSFET?

Apologies if that is something obvious, but I`m really new to semiconductors and material science.

Best regards

I would like to ask, what is the difference between BFP840ESD and BFP840FESD? What does an F mean?

There is only a difference in the conversion frequency and noise coefficient between the two on the data sheet, and the packaging is different. What are the other differences

I would like to check the possibility of using BGS18MA12 Rf switch for an RFID HF 13.56Mhz project.

I would like to use it to attached multiple antennas to a single transceiver and each time select a different antenna.

The issue is that the IC is rated with a minimum frequency of 100Mhz but regardless of this, I want to know if there is any chance that this IC will work in the RFID case?

IF not, is there a similar alternative to the BGS18MA12 that will work for the 13.56MHz band?

Thanks

Hi,

I need a power amplifier that will be used in 4G LTE Band 65 (2100-2200 MHz). The power output needed is 1W.

The device will be used in a cubesat so high efficiency is also needed.

Is there any product that you can recommend me for such an application?

Thanks!

I wanted to check what suffix H6327  stand for in part number BAT6405W H6327

and if there is any link to this in the Infineon website for future reference, Thank you 

Hi Infineon

We know the BGA525N6 absolute maximum ratings for temperature (-40~-85) , can you tell us the recommended operating temperature conditions, thank you !

Hello, 

I am trying to solder the  BGS14M8U9  onto a PCB with a Pick & Place robot wich also dispenses the Paste. I`m looking for the right volume or mass of paste becaus of its impact on the line impedance

From the datasheet i can see that the stencil pad has a diameter of 0.25 mm but there is no information about the thickness or aspect ratio of the stencil for calculating the volume.

How can i calculate the right amount of solder paste?

Any recommendations or values based on experience?

Best regards.

Hi,

I want to make a small signal analysis of the BGB707L7ESD. For this s2p files are provided.

In their measurement setup Vbias is decoupled from the RF path. However, in the reference designs of the design guide the Vbias pin is part of the RF matching. 

So in order to make a proper simulation one would need a s1p file for that pin or some SPICE model. However, this is not offered by Infineon. 

How should I proceed? 

Thanks

Hello everyone,

I am working on my master thesis project developing a high frequency (<3 GHz) photodiode amplifier, and was wondering if someone could supply me with the PCB design files of any of the BFP dev boards. Unfortunately, distributors don't seem to have them in-stock, and I am planning to use it as a template to give me a head start and save me some time.

Best regards!
