4210-52

Overview

The pSemi 4210-52 is a single-pole double-throw (SPDT) RF switch IC designed for general-purpose applications. It operates within a frequency range of 10 MHz to 3 GHz and supports a supply voltage of 2.7 V to 3.3 V. The device features an insertion loss of 0.45 dB, isolation of 25 dB, and an input IP3 of 33.5 dBm. It utilizes a reflective topology with a 50 Ohm impedance and includes DC blocking capabilities. The component is housed in an 8-MSOP package and functions across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement processes. Confirm that the 8-MSOP package dimensions align with existing PCB footprints. Ensure that the 2.7 V to 3.3 V supply voltage range is compatible with the system design. Check for available replacement alternatives if long-term supply stability is required.

Selection Notes

Select this component when a compact SPDT switch with single-line control is needed for frequencies up to 3 GHz. Consider the 0.45 dB insertion loss and 25 dB isolation specifications for signal integrity requirements. Evaluate the 8-MSOP package size against board space constraints. Verify compatibility with the 2.7 V to 3.3 V operating voltage range.

Part Context

The 4210-52 belongs to the pSemi UltraCMOS family of RF switches, which are known for integrating CMOS control logic on-chip. This series typically offers low insertion loss and high isolation in small surface-mount packages. The device represents a solution for managing RF signals in space-constrained applications requiring efficient control interfaces.

Replacement Considerations
