The HMC129LC4 from Analog Devices Inc. is a high-performance, double-balanced mixer designed to meet the demanding requirements of RF and microwave communication systems. This GaAs MMIC (Gallium Arsenide Monolithic Microwave Integrated Circuit) mixer is ideal for applications requiring a broad frequency range and excellent isolation between ports.

Key Features:

• Wide Frequency Range: The HMC129LC4 operates effectively across a wide frequency range, with the RF and LO (Local Oscillator) frequency from 11 to 20 GHz and the IF (Intermediate Frequency) from DC to 3 GHz. This makes it suitable for a variety of applications, including satellite communications, point-to-point and point-to-multipoint radios, and military systems.
• High Isolation: The mixer provides excellent isolation, with a typical LO to RF isolation of 42 dB and LO to IF isolation of 40 dB. This high level of port isolation ensures minimal leakage between signal paths, leading to improved system performance.
• Conversion Loss: With a conversion loss of typically 9 dB, the HMC129LC4 maintains a good balance between conversion efficiency and linearity, making it an effective choice for systems where both are critical.
• Package: Housed in a compact 4x4 mm surface-mount leadless ceramic package (LC4), the HMC129LC4 is designed for easy integration into a wide range of electronic assemblies.

Applications:

• Satellite Communications
• Test Equipment and Sensors
• Point-to-Point and Point-to-Multipoint Radios
• Military & Space
• Electronic Warfare and ECM
