CGH31240F

Overview

The CGH31240F is a gallium nitride (GaN) amplifier operating from 2.7 to 3.1 GHz, housed in a ceramic/metal flange package. It delivers a saturated output power of 240 W with a large signal gain of 12 dB and a drain efficiency of 60%. The device features an internally matched 50-ohm input for simplified integration. Electrical specifications are measured at VDS = 28 V, IDQ = 1 A, and TC = 25°C under pulsed conditions.

Feature Summary

• High-efficiency GaN HEMT technology optimized for wide bandwidth applications
• Internally matched 50-ohm input impedance eliminates external matching networks
• Robust thermal management capabilities supporting high junction temperatures

Applications

• S-Band radar systems
• General RF amplification circuits

Procurement Notes

Verify the specific revision status against the latest MACOM datasheet before finalizing designs. Confirm that the ordering suffix matches the required component type, as the base part number refers to the discrete amplifier while other suffixes may indicate evaluation boards or sample kits. Ensure all handling procedures strictly follow electrostatic discharge protocols.

Selection Notes

Select this component for S-Band applications requiring high output power and broad operational bandwidth. The internal 50-ohm matching simplifies circuit design compared to unmatched devices. Verify that the system can accommodate the specified 28 V drain voltage and 1 A quiescent current requirements to ensure optimal performance within the absolute maximum ratings.
