This application has four calculation functions for RF Engeneer .

1) dBm to W and W to dBm calculator .
2) ATT value in dB to each Resistors of circuit .
3) Resistors of circuit to ATT value and Impedance.
4) Resistance connected parallel .
Picker Wheel Data setting interface is very simple for all functions .

DETAILS of functions

1) dBm/W
Set the power value in dBm using numeric Wheel ,
It can input below the decimal point using last wheel.
Power value in W will calculate above area .
The unit is changed by the value Ex: µW,mW,W,kW .
Minus dBm value is possible from 0.01µW , using [+/-] Wheel.
Using last wheel to set µW/mW/W/kW , you can calculate W to dBm .
The first wheel will change to numeric Data in while you set the unit to µw~kW .

This calculate is based on 0dBm = 1mW .

2) dB-R
Choose ATT type [π] or [T] ,
schematics will changeπ type orT type .
Select ATT value with right Wheel .
R1,R2,R3 values will calculate above area .
Resistor value is a calculated value ,not E24 numbers.

3) R -dB
Choose ATT tpe [π] or [T] ,
schematics will change π type or T type .
Select R1 and R2 value with 2 Wheels .
ATT Value will calculate above area,and calculated total impedance in Ohm .
The impedance must select nearest value with transmission lines impedance .
The value of resistor is selected from the E24 numbers.

4) R1//R2
Select R1 and R2 value with 2 Wheels .
Parallel Value will calculate above ,

Note: info Button will show current version , and you can go to Support URL .
