Do you have any recommendations for the RF Switches (for an external Low Noise Amplifier) when connected to the DW3000 working at 8.5GHz?

Hi David,

You may use this RF switch in the link below. It has a 0.65dB typical insertion loss at 8GHz.

Thanks, I will give this a try!

You can also use the Qorvo QM12112 switch with matching for UWB frequencies.

Thanks, I looked at these but I was a little concerned about the switching speed especially when using the very short chirps of the DW3000.

Hi David,

I assume you need these switches to bypass the LNA for TX operation.
Switching between TX and RX should not be a problem with these two switches that I suggested.

What is the purpose of using these switches and what is your required switching speed requirement?

Best regards,
Emre
