General Description

The MAX2058 high-linearity digital-variable-gain ampli-

fier (DVGA) is designed to provide 62dB of total gain

range and typical output IP3 and output P1dB levels of

+32.3dBm and +19dBm, respectively. The device is

ideal for a variety of applications, including RFID hand-

held and portal readers, as well as single and multicar-

yields a high level of component integration, which

includes two 5-bit, 31dB digital attenuators, a two-stage

driver amplifier, a loopback mixer, and a serial interface

to control the attenuators.

The MAX2058 is pin compatible with the MAX2059

1800MHz to 2200MHz DVGA, facilitating an easy

design-in for applications where a common PC board

layout is used for both frequency bands.

The MAX2058 is available in a 40-pin thin QFN pack-

age with an exposed paddle. Electrical performance is

guaranteed over a -40°C to +85°C temperature range.
