**A Technical Overview of the HMC1163LP5E Ka-Band Power Amplifier MMIC**

The **HMC1163LP5E** represents a significant advancement in **monolithic microwave integrated circuit (MMIC)** technology, engineered to address the demanding requirements of modern high-frequency systems. Operating within the **Ka-Band spectrum from 27 GHz to 31 GHz**, this power amplifier is designed for applications including point-to-point radio, satellite communications, and military/electronic warfare systems where high linearity and output power are critical.

Fabricated using a **0.15 µm gallium arsenide (GaAs) pHEMT** process, the HMC1163LP5E delivers exceptional performance. It achieves a **saturated output power (Psat) of up to 29 dBm** and a **small-signal gain of 22 dB** across the entire band. A key feature of this amplifier is its high linearity, characterized by an **output third-order intercept point (OIP3) of 38 dBm**, making it suitable for complex modulation schemes used in 5G backhaul and other high-throughput data links.

The MMIC is housed in a compact, RoHS-compliant 5x5 mm **leadless package (LP5)**, which is designed for easy integration into multi-chip modules (MCMs) and printed circuit boards (PCBs). Its structure includes on-chip DC blocking capacitors at the RF ports and bypass capacitors for stable operation. The device requires a **positive supply voltage of +5V** and typically draws **180 mA of current**, with an integrated bias circuit that ensures stable performance over temperature variations.

To ensure system robustness, the HMC1163LP5E is built with **ESD protection circuits** on all RF ports, rated to withstand Class 1C Human Body Model (HBM) levels. Its design prioritizes thermal management, with the package baseplate offering a low thermal resistance path to a heatsink, which is vital for maintaining performance and reliability in continuous operation.

**ICGOOODFIND**: The HMC1163LP5E stands out as a high-performance, highly integrated solution for Ka-Band applications, offering an optimal balance of power, gain, and linearity in a minimal footprint.
