Step Attenuator Pads 0.1 To 31.0 GHz

April 17, 2015
This 5-b digital attenuator handles 1 W power and offers a frequency range of 100 MHz to 31 GHz.

Precise attenuation control is now available in a small package and for a wide frequency range, courtesy of the model TGL2223-SM 5-b attenuator from TriQuint Semiconductor. With its wide bandwidth of 100 MHz to 31 GHz, the step attenuator provides a 15.5-dB attenuation range that is adjustable in 0.5-dB steps. Suitable for commercial and military applications, this 5-b digital attenuator features high accuracy and stability, with root-mean-square (RMS) attenuation error of less than 0.9 dB and RMS attenuation step error of less than 0.5 dB.

The tiny attenuator measures just 3.0 × 3.0 × 1.45 mm in a QFN ceramic-air-cavity surface-mount package. It is rated for power levels to 1 W (+30 dBm) and is RoHS compliant and lead free. The attenuator suffers insertion loss of 1.8 to 4.2 dB, depending upon attenuation setting and frequency, and it operates over a control-voltage range of -3.3 to -5.0 VDC. The insertion loss is less than 2 dB from 1 to 6 GHz; less than 3 dB from 6 to 18 GHz; and less than 4.5 dB from 18 to 30 GHz.

The digital step attenuator features fast switching speed of better than 30 ns. It exhibits input return loss of better than 10 dB and output return loss of better than 7 dB. It is designed for operating temperatures from -40 to +85°C.
