FAQ: HMC3587LP3BE Switching Time

Q: Can you provide the data for HMC3587LP3BE response time?

Parents
  • A: HMC3587LP3BE has VPD pin, that is much better to use for toggling the device. Response time plot is shown if Figure 1. The setup used ADL6012, a microwave envelope detector, driven by the output of HMC3587. The pink trace shows the response of the ADL6012. Turn-on delay is around 10 ns, while the turn-off delay is around 8 ns. VPD pin capacitors were removed from the evaluation board.
