Filter Design Engineer

Location: Dallas, TX
Type: Full-time

About the Role

We are looking for a skilled Filter Design Engineer to join our RF design and development team. In this role, you will design and optimize RF/microwave filters and multiplexers that are critical to next-generation wireless infrastructure, including 5G, 6G, and advanced radio systems. You will work closely with RF, antenna, and system engineers to ensure high-performance, low-loss, and reliable filter solutions for deployment in cutting-edge telecom networks.

Key Responsibilities

  • Design, model, and simulate RF/microwave filters (LC, cavity, ceramic, SAW, BAW, etc.) to meet system-level performance requirements.

  • Develop high-Q filtering solutions for sub-6 GHz and mmWave frequency bands.

  • Support the integration of filters into transceivers, radio units, and base station platforms.

  • Conduct electromagnetic simulations using tools such as HFSS, CST, ADS, or Microwave Office.

  • Collaborate with antenna and RF teams to minimize interference and optimize coexistence between bands.

  • Perform prototyping, tuning, and characterization of filters in lab and field environments.

  • Analyze filter performance across temperature, power, and environmental stress conditions.

  • Generate technical documentation, test reports, and contribute to patents and publications.

  • Stay updated on advancements in 5G/6G frequency allocations, material technologies, and miniaturization techniques to drive innovation in RF filter design.

Qualifications

  • Bachelor’s or Master’s degree in Electrical Engineering, RF/Microwave Engineering, or a related field.

  • 5+ years of experience in RF/microwave filter design within the telecom, semiconductor, or defense industries.

  • Expertise in filter design methodologies (cavity, lumped element, planar, SAW/BAW).

  • Strong skills in EM simulation and circuit design tools (ADS, HFSS, CST, Microwave Office).

  • Hands-on experience in filter prototyping, tuning, and measurement using VNAs and RF test equipment.

  • Understanding of wireless communication standards (LTE, 5G NR, and emerging 6G bands).

  • Strong analytical, troubleshooting, and communication skills.

Nice to Have

  • Experience with high-power filters for base stations and massive MIMO systems.

  • Knowledge of multiplexer and diplexer design for multi-band systems.

  • Familiarity with advanced materials (LTCC, ceramics, acoustic wave technologies).

  • Background in thermal and mechanical design considerations for RF filters.

  • Experience in semiconductor or wireless infrastructure development.
