.. 19-0512; Rev 0; 6/06 KIT ATION EVALU E L B AVAILA 700MHz to 1200MHz High-Linearity, SPI-Controlled DVGA with Integrated Loopback Mixer General Description The MAX2058 high-linearity digital-variable-gain amplifier (DVGA) is designed to provide 62d B of total gain range and typical output IP3 and output P1d B levels of +32.3d Bm and +19d Bm, respectively. The device is ideal for a variety of applications, including RFID handheld and portal readers, as well as single and multicarrier 700MHz to 1200MHz GSM/EDGE, cdma2000 ®, WCDMA, and i DEN ® base stations. The MAX2058 yields a high level of ponent integration, which includes two 5-bit, 31d B digital attenuators, a two-stage driver amplifier, a loopback mixer, and a serial interface to control the attenuators. The MAX2058 is pin patible with the MAX2059 1800MHz to 2200MHz DVGA, facilitating an easy design-in for applications where a mon PC board layout is used for both frequency bands. The MAX2058 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. o +32.3d Bm Typical Output IP3 o +19d Bm Typical Output 1d B pression Point o 700MHz to 1200MHz RF Frequency Range o 1800MHz to 2200MHz RF Frequency Range (MAX2059) o 10.5d B Typical Small-Signal Gain o Includes Two Independent 31d B Attenuator Stages, Yielding 62d B of Total Gain-Control Range with 1d B Steps o 3-Wire SPI™/MICROWIRE™-patible o Integrated Loopback Mixer for Tx/Rx Self Diagnostics o +5V Single-Supply Operation o External Current-Setting Resistors for Scalable Device Power o Lead-Free Package Available Features Applications GSM 850/GSM 900 2G and 2.5G EDGE Base Station Transmitters and Power Amplifiers Cellular cdma One™, cdma2000, and Integrated Digital Enhanced Network (i DEN) Base-Station Transmitters and Power Amplifiers WCDMA 850MHz and Other 3G Base-Station Transmitters and Power Amplifiers Transmitter Gain Control Receiver Gain...
