The DowKey 310 Series SPDT relays have high power handling capability in a small package. The ability to handle up to 3 KW at low frequencies (up to 30 MHz) is achieved with vacuum-enclosed contacts, minimizing noise and losses. This rugged switch is capable of "hot" switching 1 KW at 30 MHz with the optional special Tungsten-Molybdenum contacts to avoid pitting when switched with RF power applied. (It should be noted that even with heavy-duty construction, hot-switching will reduce the typical operational life of 1,000,000 cycles significantly - to approximately 10,000 cycles)
Typical applications for the 310 Series include:
- High Power Transmitter Switching
- Radar Pulse Forming Networks
- Phased Array Antenna Systems
- UHF/VHF Communications Systems
- Magnetic Resonance Imaging Systems
