The CGHV1F025S is a gallium nitride (GaN) high electron mobility transistor (HEMT) designed for high efficiency, gain, and wide bandwidth. It operates on a 40V rail within a 3mm x 4mm surface-mount dual-flat-no-lead (DFN) package. The device supports frequencies up to 15 GHz with a typical output power of 25 W. At 9.4 GHz, it delivers 11 dB gain and 48% drain efficiency under pulsed conditions.
Verify the specific datasheet revision prior to procurement, as MACOM reserves the right to modify product specifications without notice. Confirm that the required application circuit components align with the latest Bill of Materials provided in the official documentation. Ensure handling procedures meet the specified Electrostatic Discharge classifications to prevent damage during assembly.
Select this component when designing amplifiers requiring high output power across multiple microwave bands. The device accommodates reduced drain voltages down to 20V while maintaining performance. Evaluate thermal resistance requirements carefully, noting that junction-to-case values vary between pulsed and continuous wave operations based on the PCB layout.
This part belongs to the CGHV series of Gallium Nitride High Voltage transistors manufactured by MACOM Technology Solutions. These devices utilize a silicon carbide substrate to achieve superior high-frequency characteristics and breakdown voltage capabilities compared to standard silicon technologies.
Consult the official MACOM Product Change Notification documents for verified substitute part numbers or updated revisions. Do not assume functional equivalence with other models in the CGHV family without verifying pinout compatibility and electrical ratings against the current datasheet.
