MAX2059 19-0566 Rev 0 7/06 1700MHz to 2200MHz High-Linearity, SPI-Controlled DVGA with Integrated Loopback Mixer General Description Features The MAX2059 high-linearity digital-variable-gain amplifier +31.8dBm Typical Output IP3 (DVGA) is designed to provide 56dB of total gain range +18.4dBm Typical Output 1dB Compression Point and typical output IP3 and output P1dB levels of +31.8dBm and +18.4dBm, respectively. The device is 1700MHz to 2200MHz RF Frequency Range ideal for a variety of applications, including single and 700MHz to 1200MHz RF Frequency Range multicarrier 1700MHz to 2200MHz DCS 1800/PCS 1900 EDGE, cdma2000 , WCDMA/UMTS, and TD-SCDMA (MAX2058) base stations. The MAX2059 yields a high level of com- 10.9dB Typical Small-Signal Gain ponent integration, which includes two 5-bit digital Includes Two Independent 5-Bit Digital Attenuator attenuators, a two-stage driver amplifier, a loopback mixer, and a serial interface to control the attenuators. Stages, Yielding 56dB of Total Gain-Control Range with 1dB Steps The MAX2059 is pin compatible with the MAX2058 700MHz to 1200MHz DVGA, facilitating an easy 3-Wire SPI/MICROWIRE Compatible design-in for applications where a common PC board Integrated Loopback Mixer for Tx/Rx Self- layout is used for both frequency bands. Diagnostics The MAX2059 is available in a 40-pin thin QFN pack- +5V Single-Supply Operation age with an exposed paddle. Electrical performance is guaranteed over a -40C to +85C temperature range.
