.. 19-0566; Rev 0; 7/06 KIT ATION EVALU E L B AVAILA 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 56d B of total gain range and typical output IP3 and output P1d B levels of +31.8d Bm and +18.4d Bm, 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 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 patible with the MAX2058 700MHz to 1200MHz DVGA, facilitating an easy design-in for applications where a mon PC board layout is used for both frequency bands. The MAX2059 is available in a 40-pin thin QFN package with an exposed paddle. Electrical performance is guaranteed over a -40°C to +85°C temperature range. - +31.8d Bm Typical Output IP3 - +18.4d Bm Typical Output 1d B pression Point - 1700MHz to 2200MHz RF Frequency Range - 700MHz to 1200MHz RF Frequency Range (MAX2058) - 10.9d B Typical Small-Signal Gain - Includes Two Independent 5-Bit Digital Attenuator Stages, Yielding 56d B of Total Gain-Control Range with 1d B Steps - 3-Wire SPI™/MICROWIRE™ patible - Integrated Loopback Mixer for Tx/Rx Self Diagnostics - +5V Single-Supply Operation - External Current-Setting Resistors for Scalable Device Power - Lead-Free Package Available Features Applications DCS 1800/PCS 1900 EDGE Base-Station Transmitters and Power Amplifiers cdma One™ and cdma2000 Base-Station Transmitters and Power Amplifiers WCDMA, TD-SCDMA, and Other 3G Base-Station Transmitters and Power Amplifiers Transmitter Gain Control Receiver Gain Control Broadband Systems Automatic Test Equipment Digital and Spread-Spectrum...
