MAX2150 Wideband I/Q Modulator with Sigma-Delta Fractional-N Synthesizer General Description Features The MAX2150 is a complete wideband direct upcon- Single Voltage Supply (2.7V to 3.6V) version quadrature modulator IC incorporating a 28-bit 75MHz 3dB I/Q Input Bandwidth sigma-delta fractional-N synthesizer. The device is target- Wideband 50 RF Output: 700MHz to 2300MHz ed for applications in the 700MHz to 2300MHz frequency range. Ultra-Fine Frequency Resolution: 100mHz The super-high-resolution sigma-delta fractional-N High Reference Frequency for Fast-Switching Applications synthesizer is capable of better than 50mHz resolution when used with a 10MHz reference. Other features: fully Ultra-Low Phase Noise differential I/Q modulation inputs, an internal LO buffer, Low Spurious and Reference Emissions and a 50 wideband output driver amplifier. -1dBm RMS Output Power A standard 3-wire interface is provided for synthesizer 60dB RF Muting Control programming and overall device configuration. An on-chip low-noise crystal oscillator amplifier is also included and 34dBc Typical Carrier Suppression can be configured as a buffer when an external reference 34dBc Typical Sideband Suppression oscillator is used. Software- and Hardware-Controlled Shutdown Modes The device typically achieves 34dBc of carrier and side- band suppression at a -1dBm output level. The wide- Ordering Information band, internally matched RF output can also be disabled while the synthesizer and 3-wire bus remain powered up PART TEMP RANGE PIN-PACKAGE for continuous programming. MAX2150ETI -40C to +85C 28 TQFN-EP* The device consumes 72mA from a single +3.0V supply MAX2150ETI+ -40C to +85C 28 TQFN-EP* and is packaged in an ultra-compact 28-pin QFN package *EP = Exposed paddle. (5mm x 5mm) with an exposed pad. +Denotes lead-free package.
