Datasheet STQ-3016 Datasheet (Stanford Microdevices)

Product Description

The Stanford Microdevices’ STQ-3016 is a direct quadra­ture modulator targeted for use in a wide range of commu­nications systems. This device features a wide 2500-4000
MHz operating frequency band, excellent carrier and side­band suppression, and a low broadband noise floor.

The STQ-3016 uses silicon germanium device technology
and delivers a typical output power of -13dBm with 50dB
IM3 suppression. A shutdown feature is included that,
when enabled, attenuates the output by 60dB.
