4272-52

Overview

The pSemi 4272-52 is an UltraCMOS RF switch IC featuring a Single-Pole Double-Throw (SPDT) configuration. It operates within a frequency range of 0 Hz to 3 GHz, with a test frequency specified at 2 GHz. The device exhibits a typical insertion loss of 0.6 dB and provides 34 dB of isolation. It supports a supply voltage between 2.7 V and 3.3 V and includes a single line control interface. Designed for surface mount installation in an 8 MSOP package, it functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• UltraCMOS technology enables low power consumption and high performance in a compact form factor.
• Single line control interface simplifies system integration and reduces pin count requirements.
• Absorptive design characteristics help minimize signal reflections for improved signal integrity.

Applications

• CATV distribution networks
• RF signal routing in communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing components. Confirm that the supplier provides official documentation from pSemi or authorized channels. Ensure the received parts match the 8 MSOP package type and electrical specifications. Check for compliance with relevant environmental standards such as RoHS directives before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring SPDT switching up to 3 GHz with low insertion loss. Consider the 2.7 V to 3.3 V supply range compatibility with existing logic levels. Evaluate the thermal performance within the -40°C to +85°C range against environmental conditions. Compare the 34 dB isolation specification against system noise floor requirements.
