Description
The MAX2150 is a complete wideband direct upconversion quadrature modulator IC incorporating a 28-bit sigma-delta fractional-N synthesizer. 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. Other features: fully differential I/Q modulation inputs, an internal LO buffer, and a 50Ω 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 device typically achieves 34dBc of carrier and sideband suppression at a -1dBm output level. The wideband, internally matched RF output can also be disabled while the synthesizer and 3-wire bus remain powered up for continuous programming.

The device consumes 72mA from a single +3.0V supply and is packaged in an ultra-compact 28-pin QFN package (5mm x 5mm) with an exposed pad.

An evaluation kit is available:  MAX2150EVKIT
