About this Gig

Struggling with poor antenna performance, signal loss, or reflection issues in your RF circuit? A mismatched impedance can silently kill your range and efficiency, even with a great antenna.


I design RF antenna matching networks and impedance matching circuits to get your circuit as close to 50Ω as possible, improving power transfer and reducing reflection loss.


What I offer:

  • Impedance matching network design (L, Pi, or T-network topology)
  • Smith chart-based calculations tailored to your target frequency
  • Component value selection (inductors/capacitors) for the match
  • S-parameter based simulation and verification
  • Support for antennas, filters, amplifiers, and RF circuits
  • Clear documentation for direct implementation.


Whether you're fixing an underperforming antenna, designing a new RF front-end, or matching an IC to its antenna, I'll deliver a matching network that's simulated and verified before you build it.


Send me your target frequency, source/load impedance, and any S-parameter data, and let's fix your RF performance. Message before ordering for multi-band requirements!
