| -Solutions for Low Loss Microwave and Millimeter Wave Components |
| Low-loss, high performance microwave and millimeter wave components are key parts in emerging telecommunication systems. Low loss and high performance is essential to keep signal-to-noise ratios at acceptable levels and for maintaining efficient power management in the high reliability systems. Another important parameter is to meet the cost requirements of the total system. |
