TGL2223-SMTR7

Overview

The TGL2223-SMTR7 is a wideband, 5-bit digital step attenuator manufactured by Qorvo using a 0.15um GaAs pHEMT process. It operates within a frequency range of 100 MHz to 31 GHz. The device provides a total attenuation range of 15.5 dB with a least significant bit (LSB) resolution of 0.5 dB. Key electrical specifications include a maximum insertion loss of 4.2 dB and a return loss of 18 dB. The component is designed for high reliability in demanding RF environments.

Feature Summary

• Utilizes a 0.15um GaAs pHEMT production process for robust performance
• Provides precise 5-bit digital control over signal attenuation levels
• Supports continuous wave power handling up to 20 dBm
• Features a compact surface-mount package suitable for automated assembly

Applications

• Phased array radar systems
• Electronic warfare equipment
• Test and measurement instrumentation
• Satellite communication terminals

Procurement Notes

Verify the specific suffix 'SMTR7' against official Qorvo documentation to confirm tape-and-reel packaging and lead frame material. Ensure that the ordering information matches the required RoHS compliance status and environmental certifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a wideband digital attenuation solution is required across the L, S, C, X, Ku, and K bands. The 0.5 dB LSB resolution offers fine-grained control necessary for precision beamforming applications. Consider the 4.2 dB insertion loss and thermal characteristics when designing the RF front-end. This model is suitable for designs prioritizing linearity and low phase shift variation over broad frequency spans.

Part Context

This device belongs to Qorvo's TGL series of digital step attenuators, which are engineered for high-performance microwave applications. The series utilizes proprietary GaAs technology to deliver consistent electrical performance. The TGL2223 variant specifically targets wideband operations, distinguishing itself from narrower bandwidth models within the same product family through its extended upper frequency limit.
