Hi,
I am trying to measure SAW filter operating in 2110-2170MHz which has differential Rx port. The balanced port are matched to complex load. I have Single ended antenna port.
My system cannot do balanced measurment. I have measure to single-ended measurement then combine ports and convert to correct impedance.
The target impedance is 28.4-j135.4. Passband insertion loss is >-2.8.
I have made following 3-port measurment
S11_2120 -6.71107
S12_2120 -6.15208
S13_2120 -9.10233
S21_2120 -6.18172
S22_2120 -19.5632
S23_2120 -4.179
S31_2120 -9.14166
S32_2120 -4.47585
S33_2120 -5.26386
How do I use my S-parameter values match to target impedance and calculate my passband insertion loss.
Any level of advice would help immensely.
Regards!
