Maxim MAX2058 Digital Variable Gain Amplifier Datasheet
The MAX2058 is a high‑linearity digital‑variable‑gain amplifier (DVGA) offering a total gain range of 62 dB with 1 dB steps. It integrates two 5‑bit digital attenuators, a two‑stage driver amplifier, a loopback mixer, and a 3‑wire SPI/MICROWIRE‑compatible serial interface for precise gain control.
Designed for base‑station transmitter applications, the device operates over 700 MHz to 1200 MHz RF frequencies (and 40 MHz to 100 MHz LO) and delivers typical performance of +32.3 dBm output IP3 and +19 dBm output 1 dB compression point. It is supplied in a 40‑pin thin‑QFN package and supports a single‑supply voltage of 4.75 V to 5.25 V.
