AT-263-PIN Description

Short technical summary and product information.

The MACOM Technology Solutions AT-263-PIN is a GaAs FET 5-bit digital attenuator designed for applications requiring accuracy, fast switching, and low power consumption. It provides a total attenuation of 31 dB with a minimum step size of 1 dB.

 

This attenuator operates over a frequency range of DC to 2 GHz and has a nominal impedance of 50 Ohms. Key electrical specifications include insertion loss values ranging from 2.4 dB to 3 dB across its operating frequency, and attenuation accuracy of ±0.25 dB for single bits up to 1.0 GHz. The switching speed is a maximum of 40 ns.

 

The AT-263-PIN is housed in a hermetically sealed, 16-lead ceramic surface mount package (CR-12). It is designed for lead-free and halogen-free environments, complying with RoHS standards and compatible with 260°C reflow soldering. Temperature stability is rated at ±0.18 dB from -55°C to +85°C.

 

Typical applications include dynamic range setting in precision receiver circuits and other gain/leveling control circuits where low intermodulation products are essential.
