APPLICATION

This IC is guaranteed on the test circuit constructed with 50 Ω equipment and transmission line.

This IC, however, does not have 50 Ω input/output impedance, but electrical characteristics such as conversion

gain and intermodulation distortion are described herein on these conditions without impedance matching. So, you

should understand that conversion gain and intermodulation distortion at input level will vary when you improve VS of

RF input with external circuit (50 Ω termination or impedance matching.)
