AA264-87LF

Attenuators Overview

The AA264-87LF is a GaAs integrated circuit functioning as a 4-bit digital attenuator. It operates within a frequency range of 500 MHz to 2 GHz, providing attenuation values from 2 dB to 30 dB with a least significant bit (LSB) resolution of 2 dB. The device features positive control logic and maintains a system impedance of 50 Ohms. Packaged in a 16-TSSOP format, it supports surface-mount installation for compact RF designs.

Attenuators Feature Summary

• Utilizes Gallium Arsenide (GaAs) technology for high-performance RF signal processing
• Offers precise 4-bit digital control over attenuation levels
• Supports positive control logic for straightforward interface integration

Attenuators Applications

• RF/IF signal conditioning circuits
• RFID system components
• Variable gain amplifier stages

Attenuators Procurement Notes

Verify component authenticity through authorized Skyworks channels due to potential supply chain variations. Confirm RoHS compliance status and specific packaging requirements prior to order placement. Ensure design compatibility with the 16-TSSOP footprint and thermal management needs for GaAs devices.

Attenuators Selection Notes

Select this component when variable attenuation between 2 dB and 30 dB is required in the 500 MHz to 2 GHz band. Consider the 50 Ohm impedance match for standard RF systems. Evaluate the 4-bit resolution against system linearity requirements and ensure the positive control logic aligns with available digital drive signals.
