For Military, Commercial, ATE and Telecommunications Applications
Meet dBC + CEI
Your Single Source for RF Coaxial Switches
Electromechanical (EM) and PIN diode coaxial switches are manufactured and assembled using vastly different techniques. You used to have to buy them from two different vendors who specialized in each. Not anymore!
dBC+CEI can save you time and money on PIN Diode and Electromechanical Coaxial Switches for your military and commercial applications.
5 Reasons to Buy Coaxial RF/Microwave Switches from dBC+CEI
- Save Time. Ordering is easy. Delivery is fast. And in the future if your needs change from one switch type to another, you won’t have to vet a new vendor. We’ll already be familiar with your project, your engineering team and your purchasing policies.
- Repeatability. Every dBC+CEI switch operates within the same precise parameters every cycle.
- Reliability. These high-quality switches are so reliable, they may even outlast your system!
- Support. Our design experience comes in handy for challenging applications, or if you’re trying to troubleshoot a thorny issue.
- Peace of Mind. Since 1990, dB Control has supplied mission-critical, often sole-source, products worldwide to military organizations, major defense contractors and commercial manufacturers. Charter Engineering has more than 50 years of design experience with EM switches. As dBC+CEI , they’re unbeatable.
FAQs
Q. How fast can I get the switch I need?
A. If the EM switch is in stock, we can often ship small quantities in days. If not, typical turnaround time for, say, 20 or 30 EM switches would be four to six weeks. For a standard PIN diode switch that we’ve produced before, typical lead time is eight to 10 weeks. For custom or complex switches, that time could increase to 18 to 20 weeks, depending on the amount of design involved, or if the switch requires unique materials.
Q. What if I need one kind of switch now and another kind later?
A. Regardless of the application or order size, dBC + CEI is committed to providing the most efficacious and economical solution to each customer’s requirements. With our ability to offer both EM and PIN diode switches, we’ll find one that meets your goal. Considering that both companies have been around for decades and have stellar reputations for quality and service, you can rely on us to get you the switches you need when you need them.
Q. How do I know what kind of switch I need?
A. Here are some parameters to consider:
| PIN Diode Switches | Electromechanical Switches | |
| Frequency range | From MHz to 40 GHz | From DC to 40 GHz |
| Intersection loss | Medium | Low |
| Isolation | Good at high frequencies | Good across broad frequency range |
| Repeatability | Excellent | Very good |
| Switching speed | Nanoseconds | Milliseconds |
| Power handling | Custom | Continuous |
| Operating life | Long | One million cycles on each port |
| SWaP | Small form factor | Reduced power consumption optional |
| Sensitivity | RF power overstress | Vibration |
