I will design rf antenna matching network and impedance matching circuit
RF PCB Design Specialist IoT, RFID NFC Antenna Matching Expert
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!
FAQ
What information do you need from me to start?
Target frequency, source and load impedance (or antenna S-parameters if available), and your circuit type (antenna, filter, amplifier, etc.).
Can you match multiple frequency bands (dual-band/multi-band)?
Yes, this can be done as a custom order; please message me before ordering to discuss your bands.
Will I get actual component values, not just theory?
Yes, you'll receive specific inductor/capacitor values and the matching network topology, ready to implement.
Do you provide simulation results to verify the match?
Yes, Standard and Premium packages include S-parameter simulation showing the return loss/VSWR improvement.
Can you also do the PCB layout for the matching network?
Yes, the Premium package includes a PCB layout section for the matching circuit placement and routing.
