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. Choose the plan that works for you: • Yearly subscription with a 7-day free trial. • Monthly subscription. • One-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. You can manage subscriptions in your Apple Account settings. PRIVACY No accounts. No analytics.
