HMC774A

RF Mixers Overview

The HMC774A is a general-purpose, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), double balanced mixer chip. It operates as an up-converter or down-converter within the 7 GHz to 40 GHz frequency range. The device requires no external components or matching networks for operation. Key electrical specifications include a maximum conversion loss of 14 dB and a noise figure of 13 dB. The local oscillator frequency spans 7 GHz to 22 GHz, while the intermediate frequency ranges from 0 Hz to 10 GHz. Typical performance metrics feature an input third-order intercept point (OIP3) of 20 dBm and a 1 dB compression point (P1dB) of 11 dBm. Power dissipation is rated at 189 mW. The component functions across an operating temperature range of -55°C to +85°C.

RF Mixers Procurement Notes

Verify current availability status directly with Analog Devices or authorized distributors, as supply constraints may apply. Confirm RoHS compliance details prior to procurement. Ensure handling procedures account for the die package format and sensitivity to electrostatic discharge during assembly.

RF Mixers Selection Notes

Select this component for high-frequency applications requiring passive mixing without external biasing. Consider the wide LO and RF bandwidths when designing systems operating between 7 GHz and 40 GHz. Evaluate thermal management requirements given the specified power dissipation and operating temperature limits.
