The MRFG35005NT1 is a Gallium Arsenide Pseudomorphic High Electron Mobility Transistor (GaAs pHEMT) RF power FET manufactured by Freescale Semiconductor. It operates within a frequency range of 1.8 GHz to 3.6 GHz, with a center design frequency of 3.5 GHz. The device delivers an output power of 4.5 W and requires a supply voltage of 12 V. It is packaged in a PLD-1.5 outline.
Verify the manufacturer designation, as NXP Semiconductors has acquired Freescale. Confirm the specific package variant, such as NT1 or NR5, matches the required reel quantity and tape specifications. Ensure the component meets RoHS compliance standards if applicable to the target assembly process. Cross-reference the datasheet revision to confirm electrical characteristics align with current production batches.
Select this component for designs requiring 4.5 W output power at 3.5 GHz with a 12 V bias. It is appropriate for unmatched driver stages in Class AB configurations. Consider thermal management requirements due to the power dissipation levels. Evaluate compatibility with existing impedance matching networks for the 1.8 to 3.6 GHz operational band.
This part belongs to the family of GaAs pHEMT power FETs designed for broadband wireless infrastructure. It serves as a driver amplifier stage, bridging lower-power control signals to higher-power final output stages. The PLD-1.5 package provides a compact form factor suitable for dense PCB layouts in communication equipment.
