HMC485MS8GETR

RF Mixers Overview

The HMC485MS8GETR is a high dynamic range passive MMIC mixer with an integrated LO amplifier, manufactured by Analog Devices Inc. It operates within a frequency range of 1.7 GHz to 2.4 GHz and is housed in an 8-lead Mini-MSOP surface-mount package. The device requires a supply voltage of 5 V and draws a typical supply current of 45 mA. Key electrical specifications include a noise figure of 9.8 dB. It features a temperature-compensated bias network that stabilizes quiescent current across an operating temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• Integrates a local oscillator amplifier with the passive mixer core for simplified system design.
• Incorporates a temperature-compensated bias network to maintain stable quiescent current under varying thermal conditions.
• Utilizes GaAs MMIC technology for high dynamic range performance.

RF Mixers Applications

• W-CDMA systems
• CDMA systems
• GSM systems
• UMTS up/down conversion

RF Mixers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix matches the required package variant. Check for obsolescence notices or lifecycle status updates from Analog Devices prior to finalizing procurement plans to ensure long-term availability.

RF Mixers Selection Notes

Select this component for applications requiring integrated LO amplification to reduce external circuitry complexity. Ensure the operating frequency falls within the 1.7 GHz to 2.4 GHz range. Verify that the 5 V supply voltage and 45 mA current consumption align with the system power budget. Consider the 8-MSOP-EP package dimensions for PCB layout constraints.
