| Specification Notes | |
| The spurious specification covers far-out spurs. Internal optimization can achieve 70 dBc suppression of close-in spurs. Above 11 GHz, an appropriate absorptive high-pass filter is recommended for improved spurious suppression. Additional filtering may be selected for the operating band according to the spur distribution. | |
