ZAMP003H6TA

Overview

The ZAMP003H6TA is an ultra-low current low noise amplifier (LNA) MMIC designed for L-band and intermediate frequency applications. It operates within a frequency range of 800 MHz to 2.5 GHz, featuring a typical gain of 14.8 dB and a noise figure of 5.5 dB. The device requires a supply voltage between 4.5 V and 5.5 V with a typical operating current of 6.8 mA. Packaged in a compact SC-70-6 surface-mount format, it is optimized for 50-ohm input and output impedance.

Feature Summary

• Ultra-low current consumption design suitable for space-constrained applications
• Rising gain characteristic compensates for high-frequency signal losses
• Optimized 50-ohm input and output impedance matching
• Minimal external bias component requirements

Applications

• Direct Broadcast Satellite (DBS) systems
• Set-top box signal processing
• Satellite Mobile Radio (SMR) receivers
• General-purpose L-band amplification

Procurement Notes

Verify the specific suffix against official Diodes Incorporated documentation to confirm exact package type and tape-and-reel specifications. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to confirm active status and avoid obsolete inventory substitutions.

Selection Notes

Select this component when designing circuits requiring minimal power consumption alongside stable wideband amplification. The rising gain profile makes it suitable for applications where signal attenuation increases at higher frequencies within the L-band. Ensure the system power supply can maintain the required 4.5V to 5.5V range while supporting the typical 6.8mA load current without significant voltage droop.

Part Context

This device belongs to the ZAMP series of buffer and low noise amplifiers from Diodes Incorporated. It complements other family members by offering a specialized solution for L-band frequencies with a focus on low current draw. The SC-70-6 package allows for high-density PCB layouts, making it a key component for modern portable and embedded satellite communication hardware.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the ZAMP003H6TC variant. Verify pin compatibility and electrical parameter overlaps before swapping components to ensure circuit stability and performance consistency.
