The customer is requesting the additional data other than the datasheet "Typical Performance Characteristics".
Characteristic data of the data sheet is different due to measurement conditions and data items are insufficient.
Downconverter PerformanceUpconverter PerformanceIF BANDWIDTH
e.g. P1dB ... etc.
Can you provide the the additional data ?
The datasheet has a representative sample of the mixer performance. Since a mixer is a 3 port device it is difficult to measure all possible combinations for each spec. If the customer has a specific frequency that they have a concern about then let us know.
