atn3580 series: fixed attenuator pads
features
● specified flat response to 40 ghz
● return loss > 16 db to 40 ghz
● available at 1–10, 12, 15, 20, 30 and 40 db
● power handling to 1 w cw
● rugged thin film silicon chips
the atn3580 series of attenuator chips incorporate thin film
resistors on high resistivity silicon chips to achieve precision
attenuation, tight flatness and high return loss to 40 ghz. the
design uses a balanced tee resistive structure to assure broad
bandwidth performance. the thin film technology offers improved
power handling capability in comparison to the traditional thick
film printed attenuator. all atn3580 attenuator chips are
specified for their attenuation at dc. in addition, a wafer probe
sample test is performed to 40 ghz to assure meeting the
flatness specification. skyworks’ measurements indicate that
attenuation typically increases with increasing frequency, as
shown in figure 1.
