Some calculators for radio of accounts here are given. They are
simple enough and everyone work.
Remember, that of inductance are specified in (nH) (1uH = 1000nH).
The Capacitance are specified in (pf) and the resistors are specified in Om. Decimal meanings it are not taken into account in fields of input, if you will enter meaning 1.9925 that it will be perceived as 1.

Parallel connection of two resistors
( Or consecutive condensers) |
|
The formula: general resistance = (R1 x R2) / (R1 + R2)
|
|
| Jet resistance of the condenser |
|
The formula: Jet resistance = 1 / (2 * Pi * F *
C)
|
|
| Jet resistance of the coil of inductance |
|
The formula: Jet resistance = 2 * Pi * F * L
|
|
| Frequency of a contour |
|
The formula:
F = 1 / (2 * Pi * Sqrt
(LC))
|
|
| ONE-LAYER COILS |
|
The formula: |
 |
 |
|
|
|
|
| MULTI-LAYER COILS |
|
The formula: |
 |
 |
|
|
|
|
| Attenuators - "T"
And "H" of a type |
 |
|
The formulas: |
 |
|
| Entrance / target Capacitance can be in any electrical units, which you prefer, for
example: MegaWatts, microWatts, Joules, etc. |
|
|
| The negative meaning turn out at input of
inadmissible meaning for attenuator. For example, it is impossible to
connect the device with 50-Om of line from 600-Om of a line and having
easing more than 6.78 |
|
| Attenuators - of a type |
 |
|
The formulas: |
 |
|
| Entrance / target Capacitance can be in any electrical units, which you prefer, for example: MegaWatts, microWatts, Joules
etc. |
|
|
| Again, the negative meanings turn out at inadmissible meaning for
attenuator. |
