The Sirenza Microdevices STQ-2016-3 is a direct quadrature
modulator targeted for use in W-CDMA applications. This
device features a 700-2500 MHz operating frequency band,
excellent carrier and sideband suppression, and a low broad-
band noise floor.
The STQ-2016-3 uses silicon germanium (SiGe) device
technology and delivers a typical channel power of -11 dBm
with adjacent channel power less than -65 dBc. A digital
input shut-down feature is included that, when enabled,
attenuates the output by 60 dB. The device is packaged in an
industry standard 16 pin TSSOP with exposed paddle for
superb RF and thermal ground. The STQ-2016-3Z is pack-
aged in a RoHs compliant and Green 16-pin TSSOP with
matte tin finish.
