Extreme Environment Resilience
Built as high reliability RF parts, our switches are tested for thermal shock and vibration, making them suitable for aerospace and maritime RF link components.
Rapid Prototyping
We offer fast turnaround on custom high-power transitions to help you meet your defense or 5G systems infrastructure deadlines.
Choosing the Right High Power RF Switch
Critical Factors for Heavy-Duty Signal Routing
Selecting a high-power transition is vital for RF system integration services. Our RF & microwave product expert team recommends focusing on these heavy-duty parameters:
Power Handling (CW & Peak): Our high performance RF components are rated for significant wattage. Ensure the switch can handle your transmitter’s maximum output, especially during “hot-switching” events.
Thermal Management: High power generates heat. We offer switches with integrated heat sinks and high-power shunt diode configurations to prevent junction failure in RF infrastructure components.
Switching Speed vs. Power: While coax RF switches are slower, our high-power PIN diode models provide microsecond-level speeds—essential for T/R (Transmit/Receive) switching in tactical radar.
P1dB and Linearity: Designed as high reliability RF parts, our switches maintain high 1dB compression points to ensure signal purity in satellite communications RF parts.
Technical FAQ
What is the advantage of a shunt-connected PIN diode for high power?
In high-power designs, shunt-mounted diodes are attached directly to the metal housing. This provides a direct thermal path to dissipate the heat generated by high power RF amplifiers, ensuring the switch survives long-duration transmissions.
Can these switches be used for T/R (Transmit/Receive) switching?
Absolutely. Their ability to handle high transmit power while providing high isolation to protect sensitive low noise amplifiers makes them the ideal choice for military/microwave radios and UAV communication links.
What driver requirements are needed for high power switching?
Our online RF parts shop provides switches with integrated TTL drivers. High power models often require specific bias voltages to ensure the diodes remain fully “pinched off” during high-voltage RF swings.
