General Description

The MAX2059 high-linearity digital-variable-gain amplifier

(DVGA) is designed to provide 56dB of total gain range

and typical output IP3 and output P1dB levels of

+31.8dBm and +18.4dBm, respectively. The device is

ideal for a variety of applications, including single and

multicarrier 1700MHz to 2200MHz DCS 1800/PCS 1900

base stations. The MAX2059 yields a high level of com-

ponent integration, which includes two 5-bit digital

attenuators, a two-stage driver amplifier, a loopback

mixer, and a serial interface to control the attenuators.

The MAX2059 is pin compatible with the MAX2058

700MHz to 1200MHz DVGA, facilitating an easy

design-in for applications where a common PC board

layout is used for both frequency bands.

The MAX2059 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.
