HMC570LC5

Overview

The HMC570LC5 is a compact GaAs MMIC I/Q downconverter designed for the 17 GHz to 21 GHz radio frequency range. It operates with a local oscillator frequency between 7 GHz and 12 GHz, producing an intermediate frequency output from 0 Hz to 3.5 GHz. The device delivers a small signal conversion gain of 10 dB and maintains a noise figure of 3 dB. It requires a single 3.5 V supply voltage and draws 125 mA of operating current. The component is housed in a leadless RoHS-compliant SMT package.

Feature Summary

• Integrates I/Q downconversion functionality within a compact GaAs MMIC structure
• Provides high linearity performance with specified P1dB compression point characteristics
• Utilizes a leadless surface-mount technology package for space-constrained designs

Applications

• Point-to-point microwave radio systems
• Satellite communication ground stations
• Electronic warfare and signal intelligence receivers

Procurement Notes

Verify availability status directly with Analog Devices or authorized distributors as supply may be limited. Confirm that the specific orderable part number matches the required package variant. Ensure compliance with RoHS directives if applicable to your manufacturing process. Check for any specific handling requirements related to moisture sensitivity levels before assembly.

Selection Notes

Select this component when designing systems requiring direct conversion from the Ka-band spectrum to baseband or low intermediate frequencies. Consider the 3.5 V power requirement and 125 mA current draw for thermal management and power budget calculations. Evaluate the 32-pin QFN footprint against available PCB real estate constraints.
