About this Gig

Hello and Welcome to this page

Imagine your RF product hitting first-pass success: clean S-parameters, tight radiation patterns, no unexpected losses at GHz frequencies. Thats the result I deliver.


I specialize in RF microwave antenna PCB designwhere impedance control is critical, amplifiers stay matched, GPS front-ends pull strong signals, and audio interfaces avoid RFI bleed. I've tuned patch antennas on FR4, optimized power amps for efficiency and linearity, integrated GPS + audio in compact layouts, and designed multilayer stacks ready for fabrication.


Tools I use daily: Altium Designer, Keysight ADS, Ansys HFSS, CST for accurate RF and EM simulation.


What you receive:

  • RF schematic ready from day one
  • Antenna integrated & EM-simulated
  • Matched amplifier chain
  • GPS + audio clean routing
  • Controlled impedance layout
  • EMI-aware placement & shielding
  • Full Gerber, BOM, assembly files
  • Simulation results (S-parameters, radiation plots)


Clients choose me when high-frequency designs must meet spec before prototyping.


Working on 900 MHz6 GHz RF, antennas, GPS, or audio chains? Send your specs, band, size limits, or schematics.
