HMC1084LC4

RF Switches Overview

The HMC1084LC4 is a broadband reflective GaAs MESFET SP4T switch designed for high-performance RF applications. It operates within the 23 GHz to 30 GHz frequency range and features a compact 4x4 mm ceramic surface-mount package with 24 terminals. The device provides an isolation of 26 dB, insertion loss of 3.3 dB, and an input IP3 of 43 dBm at 50 Ohms impedance. It supports an operating temperature range from -55°C to 85°C and utilizes 0/-3V logic control for switching operations.

RF Switches Feature Summary

• Reflective GaAs MESFET technology ensures robust signal handling in high-frequency environments.
• Compact 4x4 mm ceramic SMT package facilitates integration into space-constrained designs.
• Low insertion loss and high isolation characteristics maintain signal integrity across the band.

RF Switches Applications

• Point-to-point microwave radio systems
• Phased array antenna beamforming networks
• Test and measurement instrumentation

RF Switches Procurement Notes

Verify the specific suffix 'LC4' corresponds to the ceramic package variant when sourcing. Confirm that the required evaluation board, such as EVAL01-HMC1084LC4, is available if prototype testing is necessary. Ensure compatibility with 0/-3V control logic levels in the system design before finalizing procurement specifications.

RF Switches Selection Notes

Select this component for applications requiring wideband coverage between 23 GHz and 30 GHz with minimal signal degradation. The reflective topology suits systems where return loss management is critical. Consider the ceramic package for thermal stability in demanding environmental conditions compared to standard plastic packages.

RF Switches Part Context
