Pad Configuration
Qorvo’s TGL2226–SM is a wideband, 6–bit digital
attenuator fabricated using Qorvo's production
0.15um GaAs pHEMT process (QPHT15). Operating
from 0.1–15 GHz, the TGL2226–SM offers a low LSB
of 0.5 dB and provides 31.5 dB of attenuation range
while supporting low insertion loss and RMS
attenuation errors.
Using standard, negative control voltages from −3.0 V
to −5.0 V coupled with excellent broadband
performance, the TGA2226–SM is ideal for supporting
a variety of commercial and military applications.
The TGL2226–SM is packaged in a 3.0 x 3.0 mm
surface mount package, with both RF ports matched
to 50 ohms for simple system integration.
