HMC245AQS16

RF Switches Overview

The HMC245AQS16 is a low-cost, non-reflective single-pole triple-throw (SP3T) RF switch IC manufactured by Analog Devices Inc. Designed for surface mount applications in a 16-lead QSOP package, it operates from DC to 3.5 GHz with a 5V supply voltage. Key electrical parameters include an insertion loss of 0.8 dB, isolation of 36 dB, P1dB of 29 dBm, and IIP3 of 48 dBm at a test frequency of 2.5 GHz. The component features a 50 Ohm impedance and supports an operating temperature range of -40°C to +85°C.

RF Switches Procurement Notes

Verify the specific suffix 'E' or absence thereof against the manufacturer's current product status, as documentation references both HMC245AQS16 and HMC245AQS16E. Confirm RoHS compliance status and REACH regulations apply to the specific batch ordered. Ensure the 16-QSOP package dimensions match the PCB footprint requirements precisely before finalizing procurement orders.

RF Switches Selection Notes

Select this component when a non-reflective SP3T switch is required for frequencies up to 3.5 GHz. It is suitable for CATV and wireless applications where low insertion loss and high linearity are critical. Consider the 16-lead QSOP package for space-constrained surface mount designs. Evaluate thermal performance within the specified -40°C to +85°C range for the intended environment.

RF Switches Part Context

The HMC245AQS16 belongs to the HMC245 family of RF switches from Analog Devices Inc. These components are engineered as monolithic microwave integrated circuits (MMICs) providing cost-effective solutions for RF signal routing. The family typically includes variants optimized for different packaging or performance specifications within the same functional architecture.

RF Switches Replacement Considerations

Direct substitute part numbers are not explicitly confirmed in the provided public documentation. Cross-reference with other HMC245 series variants such as HMC241 if pin compatibility and frequency ranges align with system requirements. Verify electrical parameter equivalence before substitution.
