AT-110TR — Overview
AT-110TR by MACOM is a component in the RF Variable Attenuator (GaAs MMIC) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The AT-110TR is a GaAs MMIC voltage-variable absorptive attenuator from M/A-COM (now MACOM), supplied in a SOIC-8 plastic package on forward tape and reel. It operates from 0.5 to 2.0 GHz with up to 30 dB of continuously variable attenuation controlled by a single 0 to +5 V positive voltage, 2.8 to 3.3 dB typical insertion loss and 0.2 us switching speed. Typical uses are radio, cellular and GPS equipment and automatic gain/level control loops.

Parameters above are transcribed from the manufacturer datasheet for reference only. Confirm the current datasheet revision and your application conditions before design-in.
Note: Correction to the brief: this is NOT a fixed attenuator - AT-110 is a voltage-variable absorptive attenuator (30 dB range). 'TR' is the forward tape-and-reel ordering code; the bulk code is AT-110. Legacy M/A-COM part whose datasheet is marked ADVANCED/PRELIMINARY; MACOM offers MAAVSS0008 as the RoHS-compliant equivalent. External DC-blocking capacitors are required on both RF ports.
