1700MHz to 2200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer
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
EDGE, cdma2000^®, WCDMA/UMTS, and TD-SCDMA
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.
