With customer requirements and expectations shaping the design process, driven by added complexity as wireless infrastructures evolve, you must assess several factors before designing new RF filter products. In this white paper, you’ll learn:
- Why to account for the impact of temperature drifts on the frequency response before beginning the design process
- How the PIM measurement setup and specifications can affect the product
- The ways to prioritize varying requirements

Electromagnetic Compatibility (EMC) has become a key and sensitive topic for OEM’s and suppliers in many industries. Not only is it important to ensure electromagnetic problems will not occur when integrating components and devices in a system, but also to fulfil the related EMC regulations. FEKO is used for EMC to simulate problems related to Electromagnetic Interferences (EMI) and Electromagnetic Susceptibility or Immunity (EMS).

The polarization purity of an antenna system is an important characteristic, particularly in dual-polarized electronic systems, where depolarization can prevent the system’s quality objectives from being achieved. Recently, the CXR feed, a new, wide band, dual polarised feed, based on conjugate matching of the undesired cross-polar field in the QZ has been developed by MVG, significantly improving the cross-polar accuracy of standard single reflector CATR systems.
