Product Attributes

Features

• 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.
• Fully differential 1/Ω 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 onchip 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×5mm) with an exposed pad.
• Single Voltage Supply (2.7V to 3.6V)
• 75MHz 3dB I/Q Input Bandwidth
• Wideband 50Ω RF Output: 700MHz to 2300MHz
