The MAX2058 high-linearity digital-variable-gain amplifier (DVGA) is designed to provide 62dB of total gain range and typical output IP3 and output P1dB levels of +32.3dBm and +19dBm, 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 iDEN® base stations. The MAX2058 yields a high level of component integration, which includes two 5-bit, 31dB digital attenuators, a two-stage driver amplifier, a loopback mixer, and a serial interface to control the attenuators.The MAX2058 is pin compatible with the MAX2059 1800MHz to 2200MHz DVGA, facilitating an easy design-in for applications where a common 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.ApplicationsAutomatic Test EquipmentBroadband SystemsCellular cdmaOne™, cdma2000, and Integrated Digital Enhanced Network (iDEN) Base-Station Transmitters and Power AmplifiersDigital and Spread-Spectrum Communication SystemsGSM 850/GSM 900 2G and 2.5G EDGE Base-Station Transmitters and Power AmplifiersMicrowave Terrestrial LinksReceiver Gain ControlRFID Handheld and Portal ReadersTransmitter Gain ControlWCDMA 850MHz and Other 3G Base-Station Transmitters and Power Amplifiers
