RF Power Conversion Calculation, Formula, Example

RF Power Conversion Calculator

RF is the radio frequency power amplifier. This amplifier acts as the normal amplifier which converts low power RF signal into high RF power signal. RF signals has represented in terms of watts and decibels.  For human ears normally the sound is heard in decibels so its unit was invented as decibels. Losses can be easily calculated in decibels. In technically engineers used as the unit WATT using this watt it is easy to find out how much power is emitting and receiving.

Formula

Power in decibels (P_dBm) is equals to ten logarithmic ten of power milliwatts

P_dBm=10log10P_mW

Power in decibel watts is equals to ten logarithmic ten of power in watts

P_dBW=10log10P_W

Power in milliwatts is equals to ten of power decibels is reciprocal of ten

P_mW=10

Power watts is equals to ten of power in decibels is reciprocal of ten

P_W=10

Power in decibels watts is equals to power in decibel milliwatts minus of thirty

P_dbW=P_dBm−30

Where

P_dBm= Power in decibel milliwatts

P_dBW = Power in decibel watts

P_mW = Power in milliwatts

P_mW = Power in watts

Example 1

Let’s calculate power in decibel milliwatts by using RF power. Consider power in millivolts P_mW is 20 milliwatts.

Let’s apply formula

P_dBm=10log10P_mW

P_dBm = 10log10*20

P_dBm  = 13.0103 dB_m

Example 2

Let’s calculate power in decibel watts by using RF power. Consider power in watts P_W is 15.

Let’s apply formula

P_dBW=10log10P_W

P_dBW = 10log10*15

P_dBW = 11.7609

Example 3

Let’s calculate power in milliwatts by using RF power. Consider power in decibel milliwatts P_dBm = 25.

Let’s apply formula

P_mW =10

P_mW = 10

P_mW = 316.2278

Example 4

Let’s calculate power in watts by using RF power. Consider power in decibel watts P_dBW = 30.

Let’s apply formula

P_W=10

P_W = 10

P_W = 1e+300
