Description: Passive wideband fundamental mixer supporting upconversion and downconversion from 6GHz to 26GHz.
The HMC773ALC3B from Analog Devices is a general-purpose double-balanced fundamental mixer covering RF and LO frequencies from 6GHz to 26GHz. It can be used as either an upconverter or downconverter and supports an IF frequency range from DC to 8GHz.
Its passive GaAs MMIC architecture requires no DC bias. Integrated balun structures provide high LO-to-RF and LO-to-IF isolation without external matching components, helping simplify wideband microwave system design.

Wideband Frequency Conversion
The HMC773ALC3B covers multiple microwave bands with one compact mixer. Its 6GHz to 26GHz RF and LO range includes portions of the C, X, Ku and K bands, making it suitable for broadband converters, microwave receivers and multi-band test platforms.
The wide DC to 8GHz IF bandwidth gives designers additional flexibility when selecting intermediate frequencies. Both low-side and high-side LO configurations can be considered according to the required frequency plan and filtering arrangement.
Upconverter and Downconverter Operation
As a downconverter, the HMC773ALC3B converts microwave RF signals into lower-frequency IF signals for filtering, amplification and digitization.
As an upconverter, it converts an IF signal into a microwave RF output for transmitter and signal-generation applications. A nominal LO drive of 13dBm or higher is recommended for stable wideband performance.
Design Considerations
The RF and LO ports are AC-coupled and matched to 50Ω. The IF port is DC-coupled. When operation down to DC is required, the IF port must not source or sink more than 2mA.
The exposed pad and ground pins must be connected to a low-inductance RF and DC ground. The not-internally-connected pins should also be connected to ground to reproduce the conditions used for the published performance data.
Short RF traces, controlled-impedance transmission lines and sufficient grounding vias are recommended when designing across the full 26GHz frequency range.
