NE68519-T1-A

Overview

The NE68519-T1-A is a high-performance, low-noise amplifier (LNA) designed for wireless communication systems operating in the 2.4 GHz ISM band. It utilizes GaAs pHEMT technology to deliver superior noise figure and gain characteristics. The device integrates an integrated output match network, simplifying circuit design by reducing external component requirements. It operates with a single supply voltage of 3.0V to 5.0V, drawing a typical quiescent current of 20mA. Key electrical parameters include a noise figure of 1.7dB, a small-signal gain of 18dB, and a third-order input intercept point (IIP3) of +18dBm. The component is housed in a compact SOT-363 surface-mount package, suitable for space-constrained mobile applications.

Feature Summary

• Integrated output matching network eliminates the need for external RF components
• Low noise figure optimized for receiver sensitivity enhancement
• High linearity performance supports robust signal integrity
• Single-supply operation simplifies power management

Applications

• Wireless LAN (WLAN) receivers
• Bluetooth and Zigbee modules
• Mobile phone front-end modules
• GPS receiver circuits

Procurement Notes

Verify the specific suffix -T1-A against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the supplier provides traceable documentation from CEL or authorized distributors. Cross-reference the lot code with manufacturing dates to avoid obsolete stock. Confirm that the packaging matches the required reel or tape specifications for automated assembly processes.

Selection Notes

Select this component when a low noise figure is critical for weak signal reception in the 2.4 GHz band. Compare its integrated matching capabilities against discrete solutions to evaluate board space savings. Consider the 20mA quiescent current draw relative to battery-powered device constraints. Verify that the SOT-363 package dimensions fit within the designated footprint on the PCB layout.

Part Context

This part belongs to CEL's NE685xx series of LNAs, which are widely used in consumer electronics requiring reliable 2.4 GHz connectivity. The series is known for balancing performance with cost-effectiveness. The NE68519 variant specifically targets applications needing moderate gain and high linearity without complex external biasing networks.

Replacement Considerations

Check for direct replacements such as the NE68519-S8 or other variants within the same family that may offer different packaging options. Evaluate alternative LNAs from manufacturers like Skyworks or Qorvo if pin-to-pin compatibility is required for existing designs.
