General Description
The MAX2150 is a complete wideband direct upconver-
sion quadrature modulator IC incorporating a 28-bit
sigma-delta fractional-N synthesizer. The device is tar-
geted for applications in the 700MHz to 2300MHz fre-
quency range.
The super-high-resolution sigma-delta fractional-N syn-
thesizer 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 50
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 includ-
ed and can be configured as a buffer when an external
reference oscillator is used.
The device typically achieves 34dBc of carrier and side-
band suppression at a -1dBm output level. The wide-
band, 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 sup-
ply and is packaged in an ultra-compact 28-pin QFN
package (5mm
5mm) with an exposed pad.
