The 200384-01 from Millimeter Wave Systems is a Reflective Waveguide SPST Switch that operates in the Ka-Band from 26.5 to 40 GHz. It has a switching speed of less than 20 ns, with an insertion loss of less than 1.5 dB and isolation of 40 dB. The switch can handle CW input power of 23 dBm. It requires a DC supply of 5V and draws 6 mA of current. The switch is available in a gold-plated aluminum module that measures 1.40 × 1.50 × 0.73 inches with a WR-28 bi-directional waveguide interface.
The 200384-01 is ideal for Ka-band and RF test and measurement applications. In pulsed radar applications, this switch can be used in the transmitter path; it also serves to mute idle transmitter noise during receive intervals that can leak into the radar’s receiver from the transmitter and reduce radar sensitivity. This switch can also be used in the receiver path to protect the low noise amplifier from damage from transmitter pulse power during transmit intervals.
