Item Description

NOS HIGH-ISOLATION LAB SURPLUS — Genuine Radiall R573402485 SP4T Latching Coaxial Switch with TTL Drivers — 0 to 18 GHz / 12V operation — BRAND NEW / UNUSED (OPEN BOX).

Up for sale is a premium, high-frequency Radiall SP4T coaxial microwave switch in absolutely pristine, unused condition. Since used units of this exact grade routinely bring premium value, this uninstalled, brand new "Open Box" example represents a pristine option for critical automated test setups, matrix routing, or precise RF calibration benches.

Budget-Conscious Buyer Note: If you are looking for a more cost-effective solution for a secondary bench or less critical development loop, we also have certified Used units of this exact same model available in our store for less. Please check our other listings for availability.

This unit features highly reliable latching mechanisms integrated with internal TTL logic drivers, meaning it only requires temporary pulse commands to switch states, minimizing heat generation and current draw at the bench.

Technical Reference Specs:

  • Frequency Bandwidth: DC to 18 GHz

  • Supply Voltage Requirement: 12V Vcc (Note: Overvoltage on TTL inputs will permanently damage the internal logic switches).

  • Port Layout: 1 Common Input/Output port surrounded by 4 independent switched SMA channels.

  • Pin Out Configuration: Clearly silk-screened on the factory chassis label detailing E1, E2, E3, E4, Vcc, and GND points for rapid wiring integration.

Physical & Mechanical Condition: The unit is entirely immaculate. The gold-plated center pins inside all 5 SMA barrels are perfectly straight, un-marred, and clean. The mounting threads and the control interface pins show absolutely zero signs of previous insertion torque or connector wear.

Store Policy & Logistics

MEET YOUR SELLER:
I offer a wide selection of Genuine Tech and Electronics Items from some of the leading manufacturers, the majority of which are sourced directly from Tektronix. Every item presented for sale is carefully inspected and examined before listing. Where appropriate, more information is provided, with the information I think you would want to know. With very few exceptions, "Used" items are pulled from working environments (manufacturing areas, engineering, marketing or sales, and occasionally customer upgrades). "New" and "New -Other" items are usually unsold overstock items. My high positive feedback rating (while selling used electronics) is a testament to the work I put in to acquire, verify and sell quality items. Buy with the utmost confidence.

TESTING:
New items are rarely ever tested. Used items are tested to the extent I have the capability. Given the wide variety of items sold, it would be impossible to test everything. I rely on my sourcing methods and provenance to only sell good working units, and any item not working is listed as such. Many items in store are decades old, and will have imperfections. They may also be subject to the hazards of transportation. Electronics also fail, and are sometimes intermittent. In the unlikely event an item differs materially from what is listed I will gladly work with you to resolve any issues. Unless stated, items are never calibrated before sale.

DOMESTIC SHIPPING:
All items will be appropriately packaged and shipped to you using the fastest possible method given what you have paid for shipping. Free shipping items are also shipped with the fastest reasonable method. Most items are shipped the same day from the west coast, ensuring items get to you even faster.

INTERNATIONAL SHIPPING:
I have had the pleasure of selling to customers in all parts of the world. Thank you for your trust over the years. Most items are available to purchase through the eBay Global Shipping Program. I am also able to ship items to most countries directly, using your account. This includes high value items that require export documentation. I do charge for this as it is very time consuming. Please contact me directly before buying if you wish to have items shipped directly to you.

PAYMENTS:
Standard payment methods are accepted. For high value purchases, I can also accept wires. Buyer pays all wire fees, including any charged by my bank. Please contact me directly before to discuss these options.  

RETURNS: 
In the unfortunate event that you believe the items needs to be returned, please be sure to contact me first. Because of the complexity of international transactions, international returns are not accepted. Please ask all questions before purchasing. Refunds for returned items are promptly processed once item is confirmed to be as it was shipped (unopened/unaltered/quantity).
