We have three questions about the PA (HMC453ST89) and phase shifter (HMC934LP5E) .Per the data sheet of the PA (HMC453ST89) , it says that the Pin#1 is DC coupled. Does this mean it is already internally biased?or should we include a biasing network?
We need to operate the PA at 1.1 to 1.2 GHz and we need to modify the application circuits of 900 MHz. So, do have SPICE/design models for this PA product and this phase shifter?
We need the evaluation PCB layouts of
