NESG220034-T1-A

Overview

The NESG220034-T1-A is an NPN SiGe RF transistor designed for UHF-band applications, featuring low noise and low distortion amplification capabilities. Manufactured using SiGe HBT technology (UHS2), it offers a transition frequency (fT) of 11.5 GHz. Key electrical specifications include a typical noise figure (NF) of 0.7 dB at VCE = 5 V, IC = 10 mA, and f = 1 GHz. The device provides a typical output power (PO 1dB) of 22.5 dBm and an OIP3 of 35 dBm under standard bias conditions (VCE = 5 V, IC = 40 mA). It delivers a maximum stable power gain (MSG) of 12.5 dB at 1 GHz. The component is housed in a 3-pin Power Minimold package.

Procurement Notes

Verify the specific suffix '-A' against official Renesas documentation to confirm if it denotes a distinct revision or packaging variant, as datasheets often list 'NESG220034-T1'. Ensure the source document explicitly links this exact part number to the provided electrical parameters. Cross-reference the manufacturer's current product status to confirm availability and design-in recommendations.

Selection Notes

Select this component when designing UHF-band circuits requiring minimal noise addition and high linearity. The 11.5 GHz fT supports operation well beyond the primary 1 GHz specification point. Consider the 3-pin Power Minimold package constraints for thermal management and PCB layout. Verify that the required bias conditions (5V supply, specific collector currents) align with the system power budget.

Part Context

This part belongs to the NESG2xxx series of SiGe transistors from Renesas Technology Corp (formerly NEC). It represents an improvement over earlier iterations regarding ESD robustness. The -T1 suffix typically indicates tape-and-reel packaging, while the -A suffix may denote a specific manufacturing lot or minor revision; however, only official datasheets can confirm functional equivalence or differences between these suffixes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Direct replacement requires verifying pinout compatibility and ensuring equivalent S-parameters and thermal characteristics. Consult Renesas application notes for recommended alternatives within the SiGe HBT portfolio if this specific part is obsolete.
