Amplifier system and device
The disclosure discloses an amplifier system and a device The amplifier system includes: at least two stages of amplifiers which are sequentially connected, wherein a static working current value of an Nth-stage amplifier in the at least two stages of amplifiers is a value obtained by decreasing a first value by a first pre-set multiple, and a static working current value of an (N−1)th-stage amplifier in the at least two stages of amplifiers is a value obtained by increasing a second value by a second pre-set multiple; the first value is a recommended static working current value corresponding to the Nth-stage amplifier, wherein N is any integer greater than or equal to 2; and the second value is a recommended static working current value corresponding to the (N−1)th-stage amplifier. The solution effectively improves power amplification efficiency in a case of guaranteeing a linearity of a power amplification link.
