NE85639R-T1

Overview

The NE85639R-T1 is a low-noise amplifier (LNA) module manufactured by CEL. It operates within the frequency range of 2400 to 2483.5 MHz, targeting applications in wireless communication systems. The device integrates a GaAs MMIC die with passive components and matching networks into a compact surface-mount package. Key electrical specifications include a typical noise figure of 1.5 dB and a gain of 17 dB at 2.4 GHz. The module requires a supply voltage of 3.3 V and draws a typical quiescent current of 25 mA. It features an enable pin for power control and provides high linearity with an output IP3 of 22 dBm.

Feature Summary

• Integrated low-noise amplification solution designed for minimal signal degradation in receiver front-ends.
• Compact surface-mount footprint facilitates automated assembly and space-constrained PCB layouts.
• Includes integrated enable functionality for efficient power management during idle states.

Applications

• Wireless Local Area Network (WLAN) receivers operating in the 2.4 GHz ISM band.
• Bluetooth baseband units requiring low noise performance.
• Zigbee and other IEEE 802.15.4 compliant radio modules.

Procurement Notes

Verify the specific suffix code on the component marking against the official CEL datasheet to confirm pinout orientation and tape-and-reel packaging specifications. Ensure that the ordering information matches the exact revision level required for your design, as manufacturing updates may alter mechanical dimensions or test conditions without changing the primary model number.

Selection Notes

Select this component when a pre-matched LNA is preferred over discrete designs to reduce development time and ensure consistent noise performance. Consider the 3.3 V supply requirement and the need for an active-high enable signal. Evaluate the thermal dissipation capabilities of the PCB copper area, as the device generates heat proportional to its supply current and gain efficiency.

Part Context

This part belongs to CEL's portfolio of RF amplifier modules designed for short-range wireless standards. It serves as a direct replacement for older discrete LNA designs in legacy 2.4 GHz hardware. The module simplifies the bill of materials by combining the amplifier die with necessary biasing and matching elements into a single unit.

Replacement Considerations

Check for direct cross-reference part numbers from CEL or alternative manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute component maintains the same 2400-2483.5 MHz operational bandwidth and compatible 3.3 V supply voltage requirements.
