MW7IC2020NT1 impedance matching

[Ari3l]

Hi, I need to match MW7IC2020NT1 PA output impedance.  I would like to know:

1) According to the list on the Datasheet Figure 11, should I assume that the impedance looking towards the output signal pin is the reflected value of Zload?

2) How does Power supply value affect the listed values ? (i.e. using Vdd = 14 V instead of 28 V)

Hello,

Thank you for contacting us.

1. Yes, please see our process to measure the Zin and Zload in this application note AN1107 page 7.

2. Please note that our reference designs are stated for a specified set of operating conditions, PO, VCC and frequency. If you want to change any condition you have to adapt your circuit.

Hope this helps.
