The dB values can be added and subtracted sequentially. Here, H's value can be multiplied by 2 to get 16, then times 2 again to have 32, and times 10 to get 320 mW. Using dB conversion, it will be H + 3 dB + 3 dB + 10 dB = 16 dB. You can also have H x 10 x 2 x 2 or H x 2 x 10 x 2, which gives 16 dB just the same.

RF Receiver Architecture. An RF receiver typically consists of four main blocks: the antenna, the RF amplifier, the mixer, and the demodulator. The antenna is used to receive the RF signal and convert it to an electrical signal. The RF amplifier is used to amplify the signal before it is mixed with a local oscillator (LO) signal in the mixer.
