STQ-1016
STQ-1016Z
Product Description
The Sirenza Microdevices’ STQ-1016 is a direct quadrature modulator targeted for
use in a wide range of communications systems, including cellular/PCS, GSM,
CDMA, TETRA, and ISM datacom. This device features a wide 250 - 1000 MHz
operating frequency band, excellent carrier and sideband suppression, and a low
broadband noise floor.
Pb
RoHS Compliant
& Green Package
250 - 1000 MHz
Direct Quadrature Modulator
The STQ-1016 uses silicon germanium (SiGe) device technology and delivers a
typical output power of -9 dBm with greater than 60dB IM3 suppression. A digital
input shut-down feature is included that, when enabled, attenuates the output by
60dB. The device is packaged in an industry standard 16 pin TSSOP with
exposed paddle for superb RF and thermal ground.
The matte tin finish on Sirenza’s lead-free package utilizes a post annealing
process to mitigate tin whisker formation and is RoHS compliant per EU directive
2002/95. This package is also manufactured with green molding compounds that
contain no antimony trioxide nor halogenated fire retardants.
16 pin TSSOP with Exposed Ground Pad
Package Footprint: 0.197 x 0.252 inches, (5.0 x 6.4 mm)
Package Height: 0.039 inches (1.0 mm)
