1700MHz to 2200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer
Direct-Conversion Base-Station
Transmitter
The MAX2058/MAX2059 are designed to interface
directly with Maxim ’s direct-conversion quadrature
modulators and high-speed DACs to provide a com-
plete solution for GSM/EDGE base-station transmitter
together with the MAX2021/MAX2022/MAX2023 direct-
conversion modulators/demodulators, the MAX5873
dual-channel DAC, and the MAX4395 quad amplifier,
form an ideal total transmitter lineup. This overall sys-
tem is highly efficient and low cost, while maintaining
high linearity and low-noise performance.
