NE3520S03-T1C-A

Overview

The NE3520S03-T1C-A is a discontinued N-channel GaAs HJ-FET designed for K-band applications. It features a Micro-X plastic S03 package and delivers a typical noise figure of 0.65 dB with an associated gain of 13.5 dB at 20 GHz, VDS = 2 V, and ID = 10 mA. The device operates with a drain-to-source voltage up to 4.0 V and a gate-to-source voltage limit of -3.0 V. Maximum power dissipation is rated at 165 mW, with a channel temperature limit of +125 °C. The saturated drain current ranges from 25 to 70 mA.

Feature Summary

• Low noise figure and high associated gain optimized for K-band frequencies
• Micro-X plastic (S03) surface-mount package design
• Gallium arsenide heterojunction field-effect transistor technology

Applications

• 20 GHz band DBS LNB
• K-band communication systems

Procurement Notes

This component is officially discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Confirm that the specific ordering suffix matches the required reel quantity, as packaging options vary between standard production reels and sample quantities. Ensure compliance with RoHS directives if applicable to your region.

Selection Notes

Select this part for designs requiring low noise performance in the K-band spectrum. Verify that the circuit can accommodate the specified maximum ratings, particularly the 4.0 V drain-to-source voltage and 165 mW power dissipation limits. Consider the S03 package dimensions during PCB layout. Evaluate thermal management strategies to maintain channel temperature within the +125 °C limit under operating conditions.

Part Context

The NE3520S03 series represents a line of gallium arsenide pseudomorphic HEMTs developed for microwave applications. Manufactured originally by California Eastern Laboratories (CEL), these devices were later integrated into Renesas Electronics' portfolio. The product family targets satellite communications and radar systems where low noise and high gain are critical performance metrics.

Replacement Considerations

The datasheet explicitly lists CE3520K3 as the drop-in replacement for the NE3520S03 series.

FAQ
