RF Diode FAQ

What is the specific diode configuration for the HSMP-3862?

The HSMP-3862 utilizes a Series Pair configuration.

How does the carrier lifetime affect the device performance?

A carrier lifetime of 500 ns determines the cutoff frequency; operation above 10fc ensures the diode behaves as a current-controlled resistor rather than exhibiting nonlinear reactance.

Is a SPICE model available for simulation?

No, a standard SPICE model is not provided because it cannot accurately simulate the key characteristic of carrier lifetime.
