HMC174MS8ETR

Product Overview

HMC174MS8ETR is an RF switch IC from Analog Devices Inc., designed to route RF signals under electronic control in compact wireless, instrumentation or communication signal-chain designs. It functions as a single-pole double-throw (SPDT) device for RF paths up to 3 GHz, making it useful when a board needs to select, isolate or redirect one RF path without a mechanical relay.

In a practical RF front end, HMC174MS8ETR should be evaluated together with the antenna network, filters, LNA, power amplifier and transceiver section. Engineers normally review insertion loss, isolation, return loss, RF power handling, control timing, bias conditions and package footprint before approving the switch for production or replacement use.

Key Features

• Design Notes: verify RF port orientation, land pattern, ground stitching, ESD handling, moisture level and reel suffix before production release

Applications

HMC174MS8ETR can be used in RF front-end modules, antenna-switching circuits, receiver/transmitter path selection, filter-bank switching, test-port routing, wireless communication equipment and compact embedded RF products. Its value is to provide a controlled RF path while saving board area compared with relay-based or larger discrete switching approaches.

Typical design reviews should consider single-pole double-throw (SPDT) routing for RF paths up to 3 GHz, including antenna selection, transmit/receive path routing, filter-bank selection, test-port switching, microwave signal-chain routing, instrumentation path control. For repair, replacement or BOM-continuation projects, buyers should compare the exact suffix, package, pinout, RF port configuration, control logic and termination style with the existing board design before approving substitution.

Quality & Sourcing

Antrex Electronics can support HMC174MS8ETR sourcing with stock availability checks, RFQ quotation, date code review, package confirmation and shipment arrangement. For RF switch purchasing, buyers can provide target quantity, acceptable date code, packaging preference, frequency range, application notes and inspection requirements for faster quotation support.

For quality control, Antrex Electronics can help arrange product photos, label review, visual inspection and third-party testing support when required. OEMs, EMS providers, RF module manufacturers, repair teams and electronic component buyers are welcome to send BOM lists or hard-to-find RF switch requests for sourcing assistance.
