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.
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.
