ZAMP003H6TC

Overview

The ZAMP003H6TC is an ultra-low current low noise amplifier (LNA) MMIC designed for L-band and IF applications, primarily targeting DBS systems. It operates within a frequency range of 800MHz to 2.5GHz. The device provides a typical gain of 14dB to 14.8dB with a rising gain characteristic to counteract high-frequency losses. Key electrical parameters include a P1dB of -7.5dBm to -6.5dBm, a noise figure of 5.5dB, and a supply current of 6.8mA to 8mA at 4.5V to 5.5V. It is optimized for 50-ohm input and output impedances.

Feature Summary

• Ultra-low current consumption design suitable for space and power-limited applications
• Rising gain characteristic compensates for signal losses at higher frequencies
• Optimized for 50-ohm input and output impedance matching
• Minimal external bias components required for operation

Applications

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

Procurement Notes

Verify component status as the ZAMP003H6TC is listed as obsolete in major distributor databases. Confirm availability through authorized channels or secondary markets if production integration is required. Ensure compliance with RoHS standards and lead-free specifications as documented in official datasheets. Validate package integrity for SC-70-6 surface mount configuration prior to assembly.

Selection Notes

Select this component for designs requiring low noise amplification in the 800MHz to 2.5GHz range with strict current constraints. The rising gain profile makes it suitable for wideband applications where uniform response is needed across the spectrum. Consider the SC-70-6 package size for compact PCB layouts. Evaluate thermal performance and supply voltage stability within the 4.5V to 5.5V operating window.
