**HMC498LC4TR-R5: A 6-12 GHz GaAs MMIC Medium Power Amplifier for Microwave Radio and VSAT Systems**

The **HMC498LC4TR-R5** is a high-performance **GaAs MMIC (Gallium Arsenide Monolithic Microwave Integrated Circuit) medium power amplifier** designed to meet the rigorous demands of modern microwave communication infrastructure. Operating across a broad **6 GHz to 12 GHz frequency range**, this amplifier serves as a critical component in applications such as point-to-point microwave radio, satellite communication uplinks, and **VSAT (Very Small Aperture Terminal)** systems, where signal integrity and output power are paramount.

Fabricated using a **0.25 µm GaAs pHEMT process**, the device delivers exceptional performance characteristics. It provides a typical **+24 dBm output power at 1 dB compression (P1dB)** and a robust **+33 dBm output third-order intercept point (OIP3)**, making it an excellent driver stage for high-power amplifiers or a final power stage in less demanding links. This high linearity is crucial for maintaining the signal quality of complex modulation schemes used in modern data links, minimizing distortion and adjacent channel interference.

A key advantage of the HMC498LC4TR-R5 is its integrated design. The **MMIC architecture incorporates all matching elements**, making it essentially 50-ohm matched for both input and output. This eliminates the need for external radio frequency matching components, simplifying board design, reducing the overall bill of materials (BOM), and minimizing physical footprint. The amplifier requires a single positive supply voltage ranging from +5V to +8V, drawing a typical current of 180 mA, and is housed in a compact, RoHS-compliant **4x4 mm leadless chip carrier (LCC) package** suitable for high-volume automated assembly.

The combination of wide bandwidth, high linearity, and integrated functionality makes the HMC498LC4TR-R5 an ideal solution for **boosting signal strength in transceiver chains** and ensuring reliable, high-fidelity transmission over long distances. Its performance is tailored to overcome path loss and maintain the stringent signal-to-noise ratios required in professional satellite and terrestrial microwave systems.

**ICGOOFind:** The HMC498LC4TR-R5 stands out as a highly integrated, high-linearity MMIC power amplifier that simplifies design and enhances performance in critical C-band and X-band communication systems, from backhaul to satellite communications.
