MMS008AA

Product Overview

MMS008AA is a single-pole four-throw (SP4T) RF switch from Microchip Technology, designed for electronic RF signal routing in wireless front ends, microwave signal chains, communication modules and RF test equipment. The screened technical data identifies a SP4T configuration with operation up to 8 GHz, giving designers a compact semiconductor switch for selecting, isolating or redirecting RF paths under electrical control.

RF switch product family for controlled signal routing in RF and microwave systems. In a real board design, this device should be evaluated together with the antenna network, filters, LNA, PA, receiver, transmitter and host-control circuitry. The orderable package is listed as Die, so the RF-port orientation, pinout, land pattern and bias/control truth table should be checked before production release.

Key Features

• Manufacturer: Microchip Technology
• Part Number: MMS008AA
• Device Type: single-pole four-throw (SP4T) RF switch
• Switch Configuration: SP4T
• RF Frequency Range: supports operation up to 8 GHz based on the screened product record
• RF Path Structure: single common RF port routed to the selected throw path in a SP4T configuration
• Nominal RF Environment: intended for controlled-impedance RF signal paths; confirm the exact port impedance and matching requirements in the datasheet
• Package / Case: Die
• Integration Format: bare-die format for hybrid microwave assemblies or module-level integration
• Critical Datasheet Parameters: confirm insertion loss, isolation, return loss or VSWR, RF power rating, linearity, control voltage and switching time for the target band
• Design Notes: compare the RF-port order, pinout, land pattern, bias/control truth table and moisture/reel requirements with the production BOM before approval

Applications

MMS008AA can be used for multi-throw RF routing, antenna or filter-bank selection, receiver-path selection and configurable front-end switching. It is suitable where a design needs repeatable electronic switching instead of a relay, jumper or manual RF path selection, especially in compact wireless products and configurable RF assemblies.

For replacement, repair or BOM-continuation projects, buyers should compare the switch topology, usable frequency range, package footprint, RF-port arrangement and control logic with the existing board. Any substitution should also account for insertion loss, isolation, return loss, RF power level and switching behavior at the actual operating frequency.

Quality & Sourcing

Antrex Electronics can support MMS008AA sourcing with stock availability checks, RFQ quotation, package confirmation, date code review and shipment arrangement. For RF switch purchasing, buyers can provide target quantity, acceptable date code, package preference, frequency range and application details 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.
