TGL4203-SM

Overview

The TGL4203-SM is a packaged wideband analog attenuator from Qorvo, designed using the standard 0.25 um MMW pHEMT process. It operates from DC to 30 GHz with a typical insertion loss of 1.5 dB and a variable attenuation range of 16 dB. The device supports an input P1dB greater than 20 dBm at 10 dB attenuation and delivers -40 dBc IM3 at a pin/tone of 6 dBm. It requires a bias voltage between -1 V and 0 V. The component is housed in a compact 3 x 3 mm surface-mount package with 16 leads.

Feature Summary

• Wideband operation spanning DC to 30 GHz
• Variable attenuation capability up to 16 dB
• High linearity with >20 dBm input power handling
• Compact 16-lead surface mount packaging

Applications

• Point-to-point radio systems
• Fiber optic communications
• Broadband military applications
• Broadband space applications

Procurement Notes

Verify the specific suffix against official Qorvo documentation to ensure correct pinout and electrical characteristics. Confirm that the 3x3 QFN package dimensions match your PCB footprint requirements. Check for any RoHS compliance updates or end-of-life notifications directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a wide frequency range up to 30 GHz is required for signal conditioning. Ensure the design accommodates the -1 V to 0 V bias requirement. Verify that the 1.5 dB insertion loss fits within the system link budget. Consider the 3x3 mm package size for space-constrained layouts.

Part Context

This part belongs to Qorvo's portfolio of RF attenuators utilizing pHEMT technology. It is distinct from other models like the TGL2767 or RFFM4204 by its specific 30 GHz bandwidth and analog control interface. The device serves as a critical component for gain control in high-frequency transmission chains.

Replacement Considerations

Official substitutes include TGL4203. Cross-reference with related models such as TGL2767 or TGL2767-SM only if their specifications align with the required 30 GHz bandwidth and attenuation range.
