AT-42036-BLKG

Overview

The AT-42036-BLKG is a general-purpose NPN bipolar transistor housed in a surface-mount 36 micro-X package. It utilizes Avago’s 10 GHz fT Self-Aligned-Transistor process with nitride passivation and gold metalization. The device features a 4-micron emitter-to-emitter pitch and a 20-finger interdigitated geometry for easy impedance matching. Key electrical specifications include a typical P1 dB of 21.0 dBm at 2.0 GHz and 20.5 dBm at 4.0 GHz, with corresponding gains of 14.0 dB and 9.5 dB. The typical noise figure is 1.9 dB at 2.0 GHz. Absolute maximum ratings specify a collector current of 80 mA, power dissipation of 600 mW, and junction temperature up to 150°C.

Feature Summary

• High output power capability suitable for medium power applications
• Low noise figure optimized for low noise amplifier designs
• High gain-bandwidth product supporting wideband operations
• Cost-effective ceramic microstrip package design

Applications

• Low noise amplifiers in VHF, UHF, and microwave frequencies
• Wideband amplifier circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging format. The BLKG suffix indicates bulk packaging containing 100 devices per unit. Confirm that the component meets all required environmental and reliability standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high frequency performance up to 6 GHz with moderate power handling. Ensure biasing conditions align with the specified VCE and IC values for optimal noise and gain characteristics. Consider the thermal resistance and derating requirements if operating above standard ambient temperatures to maintain reliability within absolute maximum limits.

Part Context

This part belongs to the AT-42036 family of silicon bipolar transistors fabricated using a self-aligned-transistor process. The BLKG variant specifically denotes the bulk packaging configuration, distinct from tape and reel options like the TR1G suffix. The device is designed as a cost-effective solution for general-purpose high-frequency applications.

Replacement Considerations

The datasheet notes that this document obsoletes part number 5989-2653EN. Verify compatibility with existing circuit layouts when substituting older revisions or similar packages.
