**HMC322ALP4ETR: A High-Performance GaAs pHEMT MMIC Double-Balanced Mixer for 24 - 34 GHz Applications**

The **HMC322ALP4ETR** represents a state-of-the-art **monolithic microwave integrated circuit (MMIC)** double-balanced mixer, engineered to deliver exceptional performance in the challenging **Ka-band frequency spectrum** from 24 to 34 GHz. This device is an optimal solution for modern microwave systems, including point-to-point radios, satellite communications, 5G infrastructure, and military/defense electronics, where high frequency, linearity, and reliability are paramount.

Fabricated using a **high-reliability GaAs (Gallium Arsenide) pseudomorphic High Electron Mobility Transistor (pHEMT)** process, the HMC322ALP4ETR offers significant advantages over traditional mixer technologies. The pHEMT foundation provides superior electron mobility, which translates into excellent high-frequency gain and very low noise figure. A key performance metric for any mixer is its **conversion loss**, and this device excels with a remarkably low typical value of **7.5 dB** across its entire operating band. This ensures minimal signal degradation during the critical frequency translation process.

Furthermore, the double-balanced design is fundamental to its high performance. This architecture provides **excellent port-to-port isolation**, particularly between the local oscillator (LO) and the intermediate frequency (IF) ports. High LO-to-IF and LO-to-RF isolation, typically greater than 30 dB, effectively prevents the powerful LO signal from leaking into other parts of the system, thereby reducing unwanted radiation and simplifying filter design. The mixer also boasts a high **input third-order intercept point (IP3)** of up to +21 dBm, underscoring its superb linearity and ability to handle strong input signals without generating significant intermodulation distortion.

Housed in a compact, RoHS-compliant, 4x4 mm LP4 leadless package, the HMC322ALP4ETR is designed for easy integration into surface-mount assembly lines, making it suitable for high-volume manufacturing. Its robust construction ensures performance stability over a wide temperature range, catering to the demanding requirements of aerospace and outdoor wireless applications.

**ICGOOODFIND**: The HMC322ALP4ETR stands out as a premier MMIC mixer, combining the benefits of GaAs pHEMT technology with a double-balanced design to achieve low conversion loss, high isolation, and outstanding linearity for critical Ka-band applications.
