SP123DHTS

RF Switches Overview

The SP123DHTS is a reflective PIN diode switch manufactured by L3 Narda-MITEQ, designed for high-frequency RF applications. It operates within a frequency range of 2000 MHz to 18000 MHz. The component features a two-position single-throw (SP2T) configuration, providing signal path selection between one input and two outputs. Key electrical specifications include a maximum insertion loss of 2.9 dB and a minimum isolation of 60 dB across the operating band. The device utilizes direct PIN diode technology for switching control.

RF Switches Feature Summary

• Reflective PIN diode switching architecture
• Wideband operation from 2 GHz to 18 GHz
• SP2T topology for dual-path signal routing

RF Switches Applications

• RF test and measurement instrumentation
• Military communication systems
• Satellite ground station equipment

RF Switches Procurement Notes

Verify the specific datasheet version and ordering suffix with the manufacturer or authorized distributor to ensure compliance with current production standards. Confirm that the reflective termination characteristics align with system impedance requirements. Request official documentation to validate the 60 dB isolation and 2.9 dB insertion loss parameters prior to integration into critical RF designs.

RF Switches Selection Notes

Select this component when a wide bandwidth up to 18 GHz is required alongside high isolation performance. The reflective nature of the switch must be considered in circuit design to prevent signal reflections from affecting source stability. Ensure the control voltage levels are compatible with the PIN diode drive requirements specified in the technical data sheet for reliable switching operations.

RF Switches Part Context

This model belongs to the SP series of RF switches from L3 Narda-MITEQ, a brand known for microwave and RF components. The company specializes in durable, high-performance devices for demanding environments.
