HRF-SW1001TR

HRF-SW1001TR Test Switch Application Field and Working Principle

When it comes to RF switch design, there’s no better choice than the HRF-SW1001TR test switch. Developed by Harris Interconnect, this intelligent, multi-channel switch allows the user to quickly switch between test points, configure multi-channel test paths, and stage multiple measurements with a few simple commands. It is suitable for a variety of applications, including testing, prototyping, and instrumentation.

Application Field

The HRF-SW1001TR test switch is designed for use in cellular wireless applications such as GSM, WCDMA, LTE, and CDMA2000. It can be used for RF signal measurements in mobile base stations and test benches, as well as for component tests, such as amplifier and filter performance. The switch is capable of operating in a wide range of temperatures and environmental conditions, making it suitable for use in the field.

The switch provides maximum signal integrity with minimal insertion loss and return loss. It can be used for signal path determination and tests on high frequency signals up to 6GHz, as well as to measure the attenuation of RF signals at various points in the path.

Design

The HRF-SW1001TR test switch is a single-pole, double-throw switch that can connect two paths at a time. The switch is capable of switching four 1.0mm ports for single-ended operation and four 2.92mm ports for differential operation from 50MHz to 6GHz. The ports are labeled to clearly indicate which ports are connected to which test paths.

The switch is housed in a sturdy, compact package and is capable of handling up to 0.5W of power. The switch is designed for use in harsh environments and can withstand temperatures from -40 to +85 degrees Celsius. It also has an internal anti-corrugation feature that prevents RF signals from “ping-ponging” or bouncing repeatedly between paths.

Working Principle

The HRF-SW1001TR test switch is controlled by a microcontroller, which is programmed with various switching profiles. When the switch is triggered, the microcontroller sends a signal to the switch to activate the desired path. The switch then connects the appropriate ports and transmits signals as required.

The switch can be manually operated or remotely controlled with a computer. It also features a “Store & Recall” function that allows the user to save switching configurations for later use.

Conclusion

The HRF-SW1001TR test switch from Harris Interconnect is a versatile, reliable switch designed to meet the needs of the modern testbench. It can be used for a variety of applications from high frequency signal measurement to signal path determination. Its low insertion loss and wide operating temperature range make it an ideal choice for use in the laboratory and in the field.
