Product Details

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 EDGE, cdma2000®, WCDMA/UMTS, and TD-SCDMA base stations. The MAX2059 yields a high level of component 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 package with an exposed paddle. Electrical performance is guaranteed over a -40°C to +85°C temperature range.
