R573412520

Overview

The R573412520 is a general-purpose Radio Frequency (RF) switch manufactured by Radiall USA, Inc. This integrated circuit implements a Single Pole Five Throw (SP5T) configuration designed for high-frequency signal routing applications. The component operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. It features a minimum isolation of 60 dB and a maximum insertion loss of 0.5 dB. The device functions with an input third-order intercept point (IIP3) and requires an operating voltage between -10.2 V and -13 V. The operational temperature range extends from -40°C to +85°C.

Procurement Notes

Verify the specific package type and pinout configuration against the official manufacturer datasheet prior to integration. Confirm that the required bias voltage levels align with the system power supply design. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Validate thermal management requirements for the intended operating environment.

Selection Notes

Select this component when a compact solution for routing signals among five distinct paths is required at frequencies up to 18 GHz. Consider the low insertion loss specification for applications demanding minimal signal attenuation. Evaluate the 60 dB isolation capability to ensure adequate signal separation in dense RF environments. Assess the -10.2 V to -13 V operating voltage range against available system power rails. Compare physical dimensions and mounting options against board space constraints.
