HMC174MS8ETR

RF Switches Overview

The HMC174MS8ETR is a single-pole double-throw (SPDT) radio frequency switch manufactured by Analog Devices Inc. utilizing GaAs technology. It operates within a frequency range of 0 Hz to 3 GHz and is housed in an 8-lead MSOP surface-mount package. The device features low insertion loss and high isolation, designed for transmit-receive applications. It supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

RF Switches Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability should focus on remaining stock from authorized distributors or secondary market sources. Ensure that any sourced units are genuine Analog Devices products with valid traceability documentation to confirm authenticity and storage conditions prior to use.

RF Switches Selection Notes

Select this component when a low-loss SPDT switch is required for frequencies up to 3 GHz in space-constrained designs. The MSOP-8 package suits applications needing minimal board area. Consider the discontinuation status and evaluate alternative switches from the manufacturer's current portfolio if long-term supply stability is critical for the product lifecycle.

RF Switches Part Context

The HMC174MS8ETR belongs to the HMC174 series of RF switches from Analog Devices. It is part of the broader Wireless & RF Integrated Circuits category. The device is specifically engineered for cost-effective solutions in wireless infrastructure and portable devices requiring reliable RF path switching with minimal signal degradation.

RF Switches Replacement Considerations

The HMC174MS8E is the non-trimmed variant of the same device family. Direct substitutes may include other SPDT switches from Analog Devices' current lineup such as the HMC256 series, though pinout and parameter verification is required.
