• Manufacturer Part Number: max2058etlt
• Description: Max2058 700mhz To 1200mhz High-linearity, Spi-controlled Dvga With Integrated Loopback Mixer
• Manufacturer: Maxim Integrated Products, Inc.

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
applications. See Figure 2. The MAX2058/MAX2059,
700MHz to 1200MHz High-Linearity,
SPI-Controlled DVGA with Integrated Loopback Mixer

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.
