- 📦RF Engineer Toolkit updated to version 66.0 is a rebuild. Every calculator now shows results as you type, accepts comma or point decimals, and every formula is unit-tested against published references. Ads are gone.
New: Smith chart, impedance matching networks, attenuator designer, LC filter designer, receiver chain (NF, IP3, SFDR), amplifier linearity, antenna separation and isolation, power dividers and couplers, VSWR and return loss.
New Pro features: calculation history with search and notes, PDF and text export, custom cable and substrate library, favourites.
Fixed: RF exposure limits, Fresnel radius, cable loss coefficients, coax cutoff, CPW impedance, radar range, dB unit conversions and waveguide tables returned wrong values in earlier versions. All corrected and covered by tests.

About RF Engineer Toolkit
RF Engineer Toolkit is the calculator set RF engineers, tower and DAS technicians, PCB designers, and radio amateurs reach for every day.
45 calculators, every formula unit-tested against Pozar, Balanis, ICNIRP 2020, FCC OET-65, and manufacturer cable data — with live results, locale-aware input, and no ads.
FIELD AND SITE
• VSWR, return loss, reflection coefficient, and mismatch loss from any one value or a wattmeter reading.
• Cable loss with manufacturer coefficients (LMR, RG, Heliax, 9913), SWR loss, and ERP.
• Link budget with FSPL, cable losses, gains, sensitivity, and margin.
• Antenna downtilt and coverage, radio horizon, Fresnel zone with earth bulge and clearance.
• RF exposure against FCC and ICNIRP limits, with safe distance for public and occupational exposure.
• Antenna separation and co-site isolation, including required spacing.
• Dipole, helical, and parabolic dish design, near-field boundaries, and Doppler shift.
DESIGN AND LAB
• Smith chart with series and shunt elements, lines and stubs, exportable as an image.
• Impedance matching networks (L, Pi, T) with Q and bandwidth.
• Attenuators (Pi, Tee, bridged-T, L-pad) with E24 and E96 values and real achieved attenuation.
• LC filter designer: Butterworth and Chebyshev, low-pass, high-pass, band-pass, and band-stop.
• Receiver chain: cascaded gain, noise figure, IP3, noise floor, and SFDR.
• Amplifier linearity: P1dB, IP3, back-off, IM3, and PAE.
• Microstrip, stripline, coplanar, and differential-pair impedance with synthesis and substrate presets.
• Coax impedance, cable delay and phase, quarter-wave transformers, and skin depth.
• Power dividers and directional couplers, S-parameter conversion, and intermodulation products.
• Rectangular and circular waveguides with WR tables, cutoff, and guide wavelength.
EVERYDAY CALCULATORS
• dBm, dBW, W, V, dBV, dBµV, dBu, and dBi/dBd conversion.
• Wavelength, reactance, resonance, time constants, Ohm's law, dividers, series and parallel circuits.
FREE AND PRO
16 calculators are free, and every Pro calculator can be previewed.
