Hi Sir

we are supporting customer to design BGT60LTR11AIP chip on board . 

may I know if the bottom of the chip have any layout guide line of it?

the bottom of the chip with "flipchip" ,

does it have any rule for the top of the layer with the chip ? need to keep copper out ? or isolate form the layer ?

can we route any trace on the top layer that touch to the flipchip?

Hello, Infineon community,

I have recently placed an order for the DEMO BGT60TR13C. However, as the delivery of the product is expected to take more than 3 weeks, and I'm eager to begin my software development work, I was wondering if someone could kindly share any example raw data obtained from the DEMO BGT60TR13C. Additionally, I would appreciate guidance on how to interpret this raw data to derive azimuth, elevation, range, and velocity information.

Hi all, 

I am using the Distance2GoL radar sensor with the intent to use it with ground penetrating radar applications. Thus, my research has led me to believe that the answers to obtaining thickness of different materials lies in the reflection and absorption of the transmitted RF energy. Therefore, I am trying to recreate the Target Hold Data plot which appears in the radar GUI, in MATLAB so that I can write a function to calculate the distances between peaks and troughs because that is where the reflections occur. Does anyone know which parameters I need to access in MATLAB in order to recreate this "magnitude vs range" plot? I've attached a screenshot of the plot from the GUI that I am trying to recreate in MATLAB.

I am trying to run the range-angle-map.py script. I understand that the maximum range is derived from the device config, and I cannot change it manually. However, when I run the script, I get smaller numbers for the objects out of range. I disabled the plotting function. Instead, I changed the code in a way to print the distance and angle. 

dist = 3.353*max_index[0]/64
print("The distance is:", dist, ", The angle is:", 40*(max_index[1]-13)/13, ", max energy is: ", max_energy)

The problem is that I can detect objects in distances more than 3.3 meters; however, the reported distance is less than the actual distance. In other words, as far as the object gets further distance, the distance value starts reducing. I am pretty sure there must be a way to change the mapping function to fix this issue.
FYI, I changed some configuration values to increase the speed.

config = Avian.DeviceConfig(
sample_rate_Hz = 1_000_000, # 1MHZ
rx_mask = 5, # activate RX1 and RX3
tx_mask = 1, # activate TX1
if_gain_dB = 33, # gain of 33dB
tx_power_level = 31, # TX power level of 31
start_frequency_Hz = 60e9, # 60GHz
end_frequency_Hz = 61.5e9, # 61.5GHz
num_chirps_per_frame = 32, # 128 chirps per frame
num_samples_per_chirp = 64, # 64 samples per chirp
chirp_repetition_time_s = 0.0001, # 0.5ms
frame_repetition_time_s = 0.1, # 0.15s, frame_Rate = 6.667Hz
mimo_mode = 'off' # MIMO disabled
)

Hello,

Discovering TLI493D-W2BW sensor with python and raspberry.

I managed to establish i2c communication and found the code.zip example,
But I'm having real troubles to read the temperature :
- the value seems awfully false,
- the value doesn't change with temperature changes.

In the file code.zip,
I tried to get the temperature with :

def update_data(self):
    global data
    (count, data) = self.pi.i2c_read_device(self.h, 6)

def get_temp (self)
    self.temp = (data[3] << 4) or (data [5] >> 4)

Does anybody see a mistake here ?

Hi.

I am using XENSIV CSK BGT60TR13C.

The xensiv_bgt60trxx_get_fifo_data() contains raw signal data, but what kind of data is this?

Units, or what kind of processing is done on this data?

If you have some kind of reference, I would like to know.

Thank you.

Dear Sir,

we would like to develop 60G 2T4R radar for our  project.  however, I can't find the Dave IDE in the SDK/material.

since 24GHz 1T1R has provided it for quick start.  could help provide it for reference? thanks

Hello, 

I've read a lot on this forum and I have not found all the information i'm looking for. I'm trying to do recordings with matlab. I've currently modified the "presence detection" code in the SDK. Let's say I'm at 50 CM from the radar, I extract the power of the fft bin to which 50cm corresponds. What does the power correspond to ? Is it the value i need to use to know if my chest is approching or getting further from the radar ?

I guess my question is : is the power value of the range fft what allows us to know the velocity and direction of an object ? If it's not the case I do not understand how you retrieve speed values from this radar. I used to use the distance2go but I had I/Q information. Only having the I information from the radar has made me loose all my senses

I hope I was clear. I will willingly give more information if necessary.  

Hello,

I'm following "2 Getting started guide of AN615" and trying to connect using the Radar GUI tool.
But the connection fails with an error. (AN615 page 10 of 32 STEP 😎
(Tried Radar GUI versions 2.8.2.202205190911 and 2.8.1.202110151545)
Please let me konw solution.

Best regards,

Dear Sir,

I would like to use 24G radar for  the application of person tracking about 5 spots (people)

may I know whether BGT24LTR22  or BGT24LTR24 can implement it?

also regarding to the BGT24xxx , how's the MAX. speed/distance/resolution detected capability?

thanks.
