General Description
The MAX2720/MAX2721 are low-cost, high-performance,
direct I/Q modulators designed for use in wideband-
CDMA and wireless local-loop (WLL) systems. Their
direct-upconversion architecture reduces system cost,
component count, and board space compared to
devices with dual-conversion architectures.
The MAX2720/MAX2721 include an I/Q modulator, a
variable gain amplifier (VGA), and a power amplifier
(PA) driver. The quadrature modulator accepts differential
baseband I/Q signals and directly modulates an RF
carrier in the 1.7GHz to 2.1GHz range (MAX2720) or
the 2.1GHz to 2.5GHz range (MAX2721). The VGA pro-
vides 35dB of output power control. The modulator’s
amplitude and phase balance yield 35dBc of sideband
suppression and 30dBc of carrier suppression. These
devices feature an LO frequency doubler that allows
the external LO source to operate at half-frequency or
full-frequency when disabled.
The MAX2720/MAX2721 operate from a single +2.7V to
+3.3V supply and require only 77mA (MAX2720) or
86mA (MAX2721) of supply current. An additional
20mA of supply current is saved by disabling the
stand-alone PA driver. A low-power shutdown mode
further reduces supply current to less than 0.1μA. The
device is packaged in the small 20-pin TSSOP-EP with
exposed paddle to improve RF performance.
