Product Description

The Sirenza Microdevices鈥?STQ-2016 is a direct quadrature

modulator targeted for use in a wide range of communica-

tions systems, including cellular/PCS, CDMA2000, UMTS,

and ISM datacom. This device features a wide 700-2500

MHz operating frequency band, excellent carrier and side-

band suppression, and a low broadband noise floor.

The STQ-2016 uses silicon germanium (SiGe) device tech-

nology and delivers a typical output power of -11dBm 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.
