**HMC698LP5ETR: A 24 GHz to 44 GHz GaAs MMIC Medium Power Amplifier**

The **HMC698LP5ETR** represents a significant advancement in **monolithic microwave integrated circuit (MMIC)** technology, specifically engineered for high-frequency applications. This GaAs-based medium power amplifier delivers exceptional performance across an extremely broad **Ka-band and Q-band** frequency range from **24 GHz to 44 GHz**, making it a critical component in modern radar, 5G infrastructure, satellite communication, and electronic warfare systems.

Fabricated on a high-reliability **0.15 µm GaAs pHEMT** process, the amplifier is designed in a compact, RoHS-compliant 5x5 mm 32-lead LP5 package. It achieves a notable **+24 dBm saturated output power (Psat)** and **+19 dBm output third-order intercept point (OIP3)**, ensuring robust linearity for complex modulation schemes. With a high **+21 dB gain** and a gain variation of only ±1.5 dB across the entire band, it provides exceptional signal amplification stability. The device operates from a single positive supply of +5V, drawing 240 mA of current, and incorporates on-chip bias sequencing and temperature compensation circuits for enhanced reliability and ease of integration into larger systems.

A key feature of the HMC698LP5ETR is its **unmatched bandwidth**, which eliminates the need for multiple narrowband amplifiers, thereby simplifying design architecture and reducing board space. Its integrated DC blocking capacitors on both RF input and output ports further streamline the design-in process for high-frequency engineers.

**ICGOOODFIND**: The HMC698LP5ETR is a state-of-the-art MMIC power amplifier that sets a high benchmark for performance, integration, and bandwidth in the millimeter-wave spectrum, offering a powerful solution for next-generation communication and sensing systems.
