NE68830-T1-A

Overview

The NE68830-T1-A is a surface mount NPN silicon high frequency transistor from the NE688 series, manufactured by CEL. It is designed for low cost amplifier and oscillator applications requiring low noise figures, high gain, and wide dynamic range. The device features a minimum noise figure of 1.5 dB at 2.0 GHz with VCE=3V and IC=7mA. It supports a maximum collector current of 100 mA and operates up to 5 GHz. Key electrical parameters include a gain bandwidth product (fT) of 9 GHz at VCE=3V/IC=20mA, and an insertion power gain of 6.5 dB at 2.0 GHz under the same conditions. Absolute maximum ratings specify a collector-to-base voltage of 9 V, collector-to-emitter voltage of 6 V, and total power dissipation of 150 mW.

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package type matches design requirements as the NE688 series offers multiple surface mount options. Check datasheet revision dates to ensure parameter accuracy. Ensure proper ESD handling procedures are followed during storage and assembly due to device sensitivity.

Selection Notes

Select this component when low noise and high linearity are prioritized for RF stages. Compare fT and NFmin values against specific frequency requirements. Consider thermal resistance and power derating curves for ambient temperature constraints. Evaluate available package styles to match PCB layout constraints while maintaining electrical performance targets.
