If you are ready here are 2 more questions for you to practice: Read through these 2 examples and make sure that you really understand each step of them and can convert them without any difficulty. Most RF application (I would say more than 95%) has 50 ohms as resistance for the reason of consistency and convenience. Where P is the power in watts, V is the RMS (root mean square) voltage in volts, and R is the resistance in ohms. We need to know the source or load resistance so we can use this basic equation:

These all represent the signal strength sourced from a signal generator or received by the antenna.ĭBm (dB over 1 milliwatt) is power and µV is voltage, they are different units so we need to know their relationship before converting them. µV (microvolt), dBµV (dB over 1 microvolt), mV (millivolt) and dBmV (dB over 1 millivolt).Visit this post for more information about dBm. ‘1 mW is 0 dBm as a reference.’ 0 dBm = 1 mW dBm (Decibel relative to 1mW power level), one of the most-used terms in RF field.ĭBm is simply power measured relative to 1 milliwatt (1mW), therefore, it is an absolute value and has its unit.

Therefore, for the sake of convenience, knowing how to use dBm, µV, dBµV, mV and dBmV is a necessity.ĭBm is also equally useful in transmitter design and we have discussed this term in a separate article. While discussing these 4 terms, dBm, µV, dBµV, and dBmV, we will focus on very small signal strength for receiver design.įor a typical receiver, the received signal is very weak and the most popular range is between 0.2µV and 10 mV. dB, dBm, dBW, dBc Basics: Can You Clearly Tell Their Difference?.dB (Decibel) Basics, Do You Really Understand What It Is?.If you are still struggling with these terms, then you should read this post word-by-word and make sure you really understand them.īefore starting reading this article, you should read these two very helpful posts first: If you already know them well I would suggest you to quickly go through this post to see if there is anything new to you. You need to know all basics of dBm, µV, dBµV, mV, and dBmV, and how to transfer them between each other without difficulty. If you are working with a receiver, then you must clearly understand the basic knowledge mentioned in this article.
