RF Switches

Waveguide Switches

Waveguide RF switches serve as essential components in aerospace applications, allowing for swift and efficient signal routing and control in high-frequency communication and radar systems. These switches are designed to ensure seamless signal transmission and reliable connectivity, enabling optimal performance and safety.

Product Specs

Waveguide Switches

Our line of waveguide switches are designed for reliability in outdoor environments including freezing rain, sand, and dust.  A mating connector is supplied with each switch. All our switches are Anodize finished, not painted, for better heat reflection and durability, and all are RoHS and REACH compliant.

Power Connectors:
•  for WR229 through WR62 – ITT KPTO2614-19P
•  for WR42 through WR28 – ITT KPTO2614-10P

Operating Temperature:  -40 to +75 °C
Humidity:  100%
Pressure Rating:  20 psig, including driving head

Standard options are available as follows:

  • Flanges can be selected from most common North American or metric types.  Specify flange type with order.
  • Driver voltages include 12V, 24V, or 48V DC and 115V or 220V AC.  Specify driver voltage with order.
  • Weather cap for manual override control (required for outdoor environments).
  • Drive head includes Form C contacts, some of which may be replace with inhibit contacts.
