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. RF Toolkit Pro unlocks: • All 45 RF calculators. • Searchable calculation history with saved inputs. • PDF exports of calculation result sheets. • Custom cable and substrate libraries.
