5 Input and Output Connections

The LMH34400DRLEVM is equipped with 50 Ω matched SMA connectors for easy connection of signal generators and analysis equipment. VIN is the signal input connector, while VOUT is the signal output connector. Coaxial SMA connections for the ambient light cancellation (ALC) and power-down circuitry (PD) are included to aid with device characterization. Test points VREF an GND allow for easy measurement of the output bias or for the application of an external voltage bias on the signal output.
