ZABG6003Q20TC

Overview

The ZABG6003Q20TC is a six-stage GaAs/HEMT FET bias controller designed for satellite Low Noise Block downconverter (LNB) applications. It operates from a supply voltage range of 2.1V to 5.5V and supports surface mount mounting in a 20-QSOP package. The device functions within an operating temperature range of -40°C to 105°C, with a typical supply current of 1.1mA.

Feature Summary

• Provides precise bias control for six stages of GaAs or HEMT FETs
• Optimized for satellite LNB power management requirements
• Operates across a wide industrial temperature range

Applications

• Satellite Low Noise Block downconverter (LNB) systems
• GaAs FET bias regulation circuits
• HEMT FET bias regulation circuits

Procurement Notes

Verify the specific package type against your design requirements, as sources indicate both 20-QSOP and 16-UFQFN variants exist for this part number family. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before procurement. Ensure the selected variant matches the exact pinout and thermal characteristics required for your PCB layout.

Selection Notes

Select this component when designing satellite LNBs requiring multi-stage FET biasing. Consider the 2.1V–5.5V input range compatibility with standard system voltages. Evaluate the 20-QSOP versus 16-UFQFN package options based on available board space and thermal dissipation needs. Verify that the 1.1mA supply current aligns with low-power system constraints.
