Description
RF Engineer Toolkit puts a professional-grade suite of radio-frequency calculators, converters and design helpers right in your pocket. Whether you are fine-tuning a microwave link on a rooftop, designing a PCB trace at your desk or studying for your amateur-radio licence, the answers you need are only a tap away.
► POWER & dB
• Watts ↔ dBm ↔ dBW converter
• Linear gain ↔ dB, PAE, EIRP/ERP
• Power-density & exposure limits (FCC / ICNIRP)
► ANTENNAS & PROPAGATION
• Downtilt coverage, LoS horizon & Fresnel zone
• Dipole/monopole length, parabolic & helical design
• Near/Far-field boundaries, wavelength, Doppler shift
► CABLES & TRANSMISSION LINES
• Coax impedance plus loss by type & length
• Delay, phase and quarter-wave transformers
• Microstrip, stripline, CPW, differential pairs, skin depth
► RF SYSTEM ANALYSIS
• End-to-end link-budget & free-space loss
• Cascaded gain, NF, IP3, SFDR calculators
• Radar maximum range, Friis, intermodulation products
• Noise figure ↔ noise temperature, S / Z / Y / ABCD converter
► FILTERS & RESONANCE
• Tank LC and RLC resonance points
• RC/RL −3 dB filter time-constant tools
► GENERAL ELECTRONICS
• Ohm’s law, voltage divider, series/parallel R-C solvers
► WAVEGUIDE
• Rectangular & circular cutoff plus full WR catalogue
• Intuitive clean UI — no ads, no sign-ups, no data collection
• Works completely offline; perfect for field engineers
• Switch between metric & imperial units instantly
• Bookmark favourites and view underlying formulas
• Core tools are free; a single in-app upgrade unlocks the entire lab
