Project Description

  • Industry Challenges: Mobile

    Industry challenges in the Mobile segment – Increasing demand for higher power handling RF front-ends

    • With the proliferation of handsets with higher aspect ratio screens, the space available for antennas is shrinking impacting antenna performance driving RF front-ends to put out additional 1-2dB power in order to achieve the same transmitted power. As a result, 1-2dB additional power through the RF front-ends is driving higher power handling & linearity through RF filters.
    • Sprint’s High Power User Equipment (HPUE) requirement also requires Band 41 RF front-end chain to put out 3dB additional power in order to achieve better cell coverage. In future carriers in China could require narrow-band 41 to have a similar requirement thus posing a challenge to existing low power Band 41 filter solutions.
    • HPUE power requirements are expected to extend to the new 5G spectrum operating in the 2.5 to 5GHz range.
  • Industry Challenges: Mobile

    Industry challenges in the Mobile segment – 5G

    • 5G RF front-ends needs to operate at frequencies higher than traditional sub 2.7GHz
    • 5G frequencies have larger bandwidth requirements compared to existing LTE bands
    • RF filters need to meet stringent bandwidth, co-existence & power handling requirements
  • Industry Challenges: WiFi

    Industry challenges in the Wi-Fi segment – Need for high frequency coexistence filtering solutions in a compact footprint

    • Proliferation of higher-order MU-MIMO driving number of RF filter placements
    • Larger bandwidth filtering needs with 802.11ax
    • Need for compact footprint compared to bulky ceramic options
    • Need for higher frequency ( > 5GHz) filtering options
  • Industry Challenges: Infrastructure

    Industry challenges in the Infrastructure segment – 4.5G and 5G driving higher order Massive MIMO & Small Cell deployment

    • Proliferation of higher-order massive MIMO with active antennas driving number of RF filter placements and need for compact footprint compared to bulky cavity options
    • A higher need for cost-effective & high-volume SMT manufacturing
    • Larger bandwidth filtering requirements with 802.11ax
    • Higher power handling requirements 1-10W average
    • Need for higher frequency ( > 5GHz) filtering options
