MAX2058 19-0512 Rev 0 6/06 700MHz to 1200MHz High-Linearity, SPI-Controlled DVGA with Integrated Loopback Mixer General Description Features The MAX2058 high-linearity digital-variable-gain ampli- +32.3dBm Typical Output IP3 fier (DVGA) is designed to provide 62dB of total gain +19dBm Typical Output 1dB Compression Point range and typical output IP3 and output P1dB levels of +32.3dBm and +19dBm, respectively. The device is 700MHz to 1200MHz RF Frequency Range ideal for a variety of applications, including RFID hand- 1800MHz to 2200MHz RF Frequency Range held and portal readers, as well as single and multicar- (MAX2059) rier 700MHz to 1200MHz GSM/EDGE, cdma2000 , WCDMA, and iDEN base stations. The MAX2058 10.5dB Typical Small-Signal Gain yields a high level of component integration, which Includes Two Independent 31dB Attenuator includes two 5-bit, 31dB digital attenuators, a two-stage driver amplifier, a loopback mixer, and a serial interface Stages, Yielding 62dB of Total Gain-Control to control the attenuators. Range with 1dB Steps The MAX2058 is pin compatible with the MAX2059 3-Wire SPI/MICROWIRE-Compatible 1800MHz to 2200MHz DVGA, facilitating an easy Integrated Loopback Mixer for Tx/Rx Self- design-in for applications where a common PC board Diagnostics layout is used for both frequency bands. The MAX2058 is available in a 40-pin thin QFN pack- +5V Single-Supply Operation age with an exposed paddle. Electrical performance is External Current-Setting Resistors for Scalable guaranteed over a -40C to +85C temperature range.
