HMC526

HMC526 is a GaAs MMIC mixer from Hittite Microwave (now Analog Devices). It’s a compact, 50-ohm matched, double-balanced mixer used to upconvert or downconvert RF signals in front-ends such as wireless transceivers, radar, and test equipment. It has RF and LO input ports and an IF output, with internal diode-ring switching for mixing. Typical advantages include broad frequency coverage, relatively low conversion loss, good port isolation, and single-supply operation in an surface-mount package.
Key design points:
- Provide appropriate LO drive and impedance-matched RF/LO ports
- Use proper matching networks for best performance
- Consider metrics like conversion loss, isolation, IP3, and noise figure for your application
- Be mindful of DC biasing, power dissipation, and thermal management
For exact specifications (frequency range, loss, isolation, LO power, supply, packaging), refer to the latest HMC526/ADI datasheet and application notes.

8 pins. It is a GaAs MMIC RF mixer (up/down converter) with RF, LO, and IF ports (plus Vcc/GND pins depending on package).

The HMC526 is manufactured by Hittite Microwave Corporation, which is now part of Analog Devices, Inc. Hittite was a fabless semiconductor company that designs RF/microwave integrated circuits and related microwave subsystems for communications and radar applications.

HMC526 is available in an 8-lead MSOP (MSOP-8) package.
