The MAX2150ETI+ from Maxim Integrated Products is a wideband I/Q modulator with 28bit sigma-delta fractional-N synthesizer in 28 pin TQFN package. The device is targeted for applications in the 700MHz to 2300MHz frequency range. The super-high-resolution sigma-delta fractional-N synthesizer is capable of better than 50mHz resolution when used with a 10MHz reference. Featuring fully differential I/Q modulation inputs, an internal LO buffer and a 50 ohm wideband output driver amplifier. A standard 3-wire interface is provided for synthesizer programming and overall device configuration. An on-chip low-noise crystal oscillator amplifier is also included and can be configured as a buffer when an external reference oscillator is used. The wideband, internally matched RF output can also be disabled while the synthesizer and 3-wire bus remain powered up for continuous programming. Typical applications include wireless broadband, satellite uplink, LMDS and wireless base station.
