General Description
The TriQuint TGL2616 is a 5-bit digital attenuator MMIC design using TriQuint’s TQPHT15 0.15 um GaAs pHEMT process. The TGL2616 is ideally suited for a variety of wideband phased array applications, including commercial and military radars, satellite-based communication systems and electronic warfare.
The TGL2616 provides a 5-bit digital attenuator function with a nominal 4.2 dB insertion loss and RMS attenuation error of better than 0.6 dB over a bandwidth of 10-20 GHz.
The TGL2616 operates with a control and reference voltage of 3.3 to 5 V. Each device is RF tested onwafer to ensure performance compliance. The device is available in die form.
Lead-free and RoHS compliant.
Evaluation Boards available on request.
