ASNT6141-KMC

Overview

The ASNT6141-KMC is a temperature-stable linear amplifier fabricated in SiGe technology, designed for receiver-side applications in high-speed communication systems. It provides broadband variable signal amplification from DC to 12 GHz with controlled gain ranging from 0 dB to 31.5 dB via two independent external control ports (vgc1 and vgc2). The device features fully differential CML input and output interfaces with on-chip 50 Ohm termination. Key electrical specifications include a typical power consumption of 530 mW, an output 1dB compression point of 1.5 dBm at 10 GHz, and a noise figure of 15 dB. It operates on a single +3.3V or -3.3V supply.

Feature Summary

• Broadband linear amplification capability spanning DC to 12 GHz
• Variable gain adjustment through dual independent external control ports
• Integrated peak detector providing reverse-proportional amplitude monitoring
• Fully differential I/O architecture with built-in 50 Ohm termination

Applications

• High-speed communication systems
• Receiver-side signal processing
• Broadband variable signal amplification

Procurement Notes

Verify the specific ordering suffix matches the required package configuration. Confirm that the voltage supply polarity aligns with the intended PCB layout, as positive and negative supply configurations require distinct termination strategies. Ensure thermal management provisions are adequate for the specified power dissipation levels during operation.

Selection Notes

Select this component when wide bandwidth up to 12 GHz is required alongside precise gain control. Consider the integrated peak detector for amplitude monitoring needs. Evaluate the differential interface compatibility with existing system logic levels. Assess thermal requirements based on the 530 mW typical consumption and the custom CQFP package heat slug design.

Part Context

Manufactured by Advanced Science And Novel Technology Company, Inc., the ASNT6141-KMC utilizes SiGe fabrication for performance and reliability. It is housed in a custom 24-pin CQFP package featuring a center heat slug for thermal dissipation. The part complies with RoHS standards per directive 2011/65/EU.
