Elektor has an iPhone/iPad app for several months. And now Android users can have an Elektor app of their own. The Elektor RF & Microwave Toolbox app is perfect for engineers and RF technicians who need easy, reliable access to essential equations, converters, calculators, and tools.

The app includes the following handy tools:

1.Noise floor (Kelvin,dBm)

2.Amplifier cascade (NF, Gain, P1db, OIP2, OIP3)

3.Radar equation (2-way path loss)

4.Radio equation (1-way path loss)

5.Power and voltage converter (W,dBm,V,dBµV)

6.Field intensity and power density converter (W/m2, V/m, A/m, Tesla, Gauss,dBm, W)

7.Mismatch error limits (VSWR, Return loss)

8.Reflectometer (VSWR, Return loss)

9.Mitered Bend

10.Divider and Couplers (Wilkinson, Rat race, Branchline , microstrip and lumped)

11.Balanced and und balanced PI and T attenuator

12.Skin depth (DC and AC resistance)

13.PCB Trace calculator (impedance/dimensions)

14.Image rejection (amplitude and phase imbalance)

15.Mixer harmonics (up and down conversion)

16.Helical antenna

17.Peak to RMS (peak, RMS, average, CF)

18.Air Core Inductor Inductance

19.Parallel plate Capacitor

20.PI and T attenuator

21.Ohm’s Law

22.Parallel LCR impedance/resonance

23.Series LCR impedance/resonance

24.Inductor impedance

25.Capacitance impedance

26.Antenna temperature (Kelvin)

27.Radar Cross Section (RCS) calculator (Sphere,Cylinder, flat plate, corners, dBsm)

28.Noise Figure Y-Factor Method

29.EMC (EIRP, ERP, dBµV/m)

30.Noise figure converter (dB, linear, Kelvin)

31.Frequency Band Designations

32.Resistor color code (reverse lookup, 3 to 6 band)

33.Filter Design (Butterworth, Chebyshev, prototype):

34.µ-Filter Design (microstrip, stripline)

35.PCB Trace Width and Clearance Calculator
