ATN3580-07 — Overview
ATN3580-07 by Skyworks is a component in the Fixed Attenuator (thin-film silicon chip, DC-40 GHz) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The ATN3580-07 is a 7 dB fixed attenuator pad built with thin-film resistors on high-resistivity silicon, using a balanced TEE structure for broad bandwidth. It is specified for flat attenuation from DC to 40 GHz with ±0.25 dB tolerance at DC, better than 15 dB return loss across the band, and 1 W CW power handling. The die is mounted directly on coplanar waveguide or microstrip and connected by bond wires or ribbons. Skyworks has discontinued the ATN3580 series; the part is now obsolete and available from independent stock.
