**HMC1097LP4ETR: A 10 W Ka-Band Power Amplifier in a 4x4 mm QFN Package**

The relentless drive towards higher data rates and more compact systems in satellite communications, 5G backhaul, and military applications has intensified the need for high-power amplification at millimeter-wave (mmWave) frequencies. Addressing this challenge, the **HMC1097LP4ETR** emerges as a pivotal solution, **integrating a robust 10 W power amplifier into an exceptionally small 4x4 mm QFN package**.

Operating over the **17 GHz to 31 GHz Ka-band spectrum**, this GaAs MMIC power amplifier is engineered for high-performance demanding roles. Its most striking feature is its ability to deliver a saturated output power (**Psat**) of **10 W (40 dBm)**. This formidable power level is crucial for overcoming path loss and ensuring strong signal integrity in long-distance point-to-point radio links and satellite uplinks. Furthermore, the amplifier provides a substantial **22 dB of large-signal gain**, significantly reducing the number of gain stages required in a system and thereby simplifying design and saving valuable board space.

Beyond raw power, the HMC1097LP4ETR is designed for linearity. It achieves an output third-order intercept point (**OIP3**) of **47 dBm**, making it suitable for transmitting complex modulation schemes found in modern communications standards without excessive distortion. Efficiency is another key benefit, with the device reaching a **power-added efficiency (PAE) of 30%**, which helps manage thermal dissipation and lowers overall system power consumption.

The integration of this capability into a **4x4 mm, 24-lead QFN package** is a significant achievement in miniaturization. The package features an exposed base for superior thermal management, which is absolutely critical for dissipating heat generated by the 10 W output power. This compact form factor allows designers to build extremely dense phased-array systems and compact radio heads without sacrificing output power.

**ICGOOODFIND:** The HMC1097LP4ETR is a benchmark MMIC power amplifier that shatters the traditional compromise between power, frequency, and size. Its combination of **10 W output power across Ka-band**, high linearity, and a **miniature 4x4 mm QFN package** makes it an indispensable component for next-generation aerospace, defense, and telecommunications infrastructure, enabling more powerful and compact mmWave systems.
