General Description

The MAX2058 high-linearity digital-variable-gain amplifier (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 handheld and portal readers, as well as single and multicarrier 700MHz to 1200MHz GSM/EDGE, cdma2000?, WCDMA, and iDEN? base stations. The MAX2058 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 package with an exposed paddle. Electrical performance is guaranteed over a -40°C to +85°C temperature range.
