Note: 1. If tap port coupling ratio is ≤ 5%, ER will be 3dB lower; for ≤1% tap port, ER is out of concern
2. The specifications are connector excluded.
3. For devices with connectors, 0.8dB higher for IL, 5dB lower for RL and 3dB lower for ER.
4. For device with connector, key aligned to slow axis if no advance requirement.
