EVAALVUAAILTAIOBNLEKIT
700MHz to 1200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer
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-
rier 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 pack-
age with an exposed paddle. Electrical performance is
guaranteed over a -40°C to +85°C temperature range.
