HMC345ALP3ETR

RF Switches Overview

The HMC345ALP3ETR is a GaAs MMIC SP4T non-reflective switch from Analog Devices, operating from DC to 8 GHz. It features low insertion loss of 2.4 dB and high isolation of 33 dB. The device supports 50 Ohm impedance with a 5V positive control supply. Key performance metrics include P1dB of 28 dBm and IIP3 of 43 dBm. It operates within -40°C to +85°C in a 16-QFN package.

RF Switches Feature Summary

• Broadband non-reflective architecture covering DC to 8 GHz
• Positive voltage control logic for simplified interfacing
• High linearity with 28 dBm P1dB and 43 dBm IIP3
• Low insertion loss of 2.4 dB at 8 GHz

RF Switches Applications

• Telecommunications base station signal routing
• Test and measurement equipment switching matrices
• Military and aerospace radar systems
• Wireless infrastructure component selection

RF Switches Procurement Notes

Verify the specific suffix 'ETR' indicates tape-and-reel packaging when ordering. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure ESD handling protocols are followed due to moisture sensitivity level 3 classification. Cross-reference the full part number to distinguish between cut tape and reel quantities.

RF Switches Selection Notes

Select this component for applications requiring broadband coverage up to 8 GHz with minimal signal reflection. The positive control voltage simplifies driver circuit design compared to negative control alternatives. Evaluate the 16-QFN footprint against available PCB real estate constraints. Consider the 5V supply requirement for power budget calculations in portable or battery-operated designs.

RF Switches Part Context

This part belongs to the HMC345 series of GaAs MESFET switches. It serves as an active replacement for the discontinued HMC345LP3ETR model. The device integrates four single-pole paths into a compact surface-mount package. It is designed for high-performance RF signal path management in demanding environments.

RF Switches Replacement Considerations

The HMC345ALP3E is listed as a similar alternative by distributors. Verify pinout compatibility and electrical specifications before substitution. The LP3 variant is obsolete; ensure the ALP3 version meets all current design requirements.
