- Above specifications are for device without connector, and the PM VOA device is both axis working. All parameters are tested at room temperature.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W.The default connector key is aligned to slow axis.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
