We don’t have second harmonic test data for these mentioned switches ADRF5044 and HMC8038.
However we have second harmonic test data for ADRF5020 which is the SPDT equivalent of ADRF5044. ADRF5044 can be expected to have similar second harmonic…
will the ADRF5044 switch function within nominal specifications using -2.5V instead of -3.3V for Vss. If not, what is the magnitude of the change in insertion loss and IP3?
I am trying to design a SP48T using ADRF5044.
On the datasheet, it says that the switch has an ideal power-up sequence:
power up GND--->Power up VDD and Vss---->Power up the digital control inputs---->Apply RF input signal
I had measured the video feed-through of ADRF5021. Below are the oscilloscope screenshots showing RF1 waveform (blue trace) during switching on at left and off and right.
The measurement was done using an ADRF5021 evaluation board. RF1 port connected…
