I would like to have information about HMC 468's P0.1dB at DC -0.25GHz.
As the data sheet, There are not information on the data sheet.
We had measured HMC624A for its power compression performance down to 1MHz. Power compression performance starts degrading below 200 MHz and becomes 10dB lower at 20 MHz.
HMC468A is designed in same process as HMC624A and expected to exhibit similar power compression degradation at low frequency range. HMC468A has typical P0.1dB spec of 26 dBm that would degrade to 16 dBm at 20 MHz. I would recommend you to evaluate HMC468A and verify its performance at your application frequency.
I hope this helps.
Unfortunately we don't have power compression test data below 200 MHz for the HMC468A. This is a GaAs attenuator so power compression performance could be expected to degrade at low frequency range. What is the minimum operating frequency in your application? I will try to give you an estimated P0.1dB value by looking at other devices (same process and similar power handling) that we already evaluated at low frequency range.
Thank you very much for your reply.
I would like to have the power compression test data at 20MHz for HMC468.
The 20MHz is our lowerst frequency.
Could you please provide the test data of power compression.
Thank you for your help.
