RF Calculators
Core RF engineering tools. Each runs client-side and is validated against standard formulas.
Wavelength & Antenna Lengths
Frequency to wavelength, half wave and quarter wave.
VSWR & Return Loss
Reflection coefficient, reflected power and mismatch loss.
RF Link Budget
EIRP, received power, link margin, PASS/FAIL.
Coax Cable Loss
Verified Times LMR and Gigatronix LBC data, typical RG references and manual entry.
dBm to Watts
RF power unit conversion.
Free Space Path Loss
FSPL, wavelength, antenna lengths.
Frequency Band Finder
Identify LTE / 5G bands from MHz.
