These relays are highly suitable for use in attenuator and other RF circuits, the RF 300 and RF303 feature:

  • High repeatability.
  • Broader bandwidth.
  • Metal enclosure for EMI shielding.
  • Ground pin option to improve case grounding.
  • High isolation between control and signal paths.
  • Highly resistant to ESD. CONSTRUCTION FEATURES The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability.
  • Uni-frame motor design provides high magnetic efficiency and mechanical rigidity.
  • Minimum mass components and welded construction provide maximum resistance to shock and vibration.
  • Advanced cleaning techniques provide maximum assurance of internal cleanliness.
  • Gold-plated precious metal alloy contacts ensure reliable switching.
  • Hermetically sealed.
  • Solderable leads.

One million cycle repeatability data is based upon 396 observations with an average repeatability ±0.033 dB and a range of ±0.093 dB. 2. Repeatability of attenuation values were obtained from tests conducted in a 20 dB attenuator network with a 0 dBm input signal. 3. Relay operates at frequencies higher than 3 GHz with reduced RF performance characteristics. 4. Curves were developed from tests performed on a 0.031" copper clad, reinforced PTFE circuit board at 20°C (ref). The un- utilized contacts were terminated in 50 ohms; characteristic impedance of measuring equipment is 50 ohms. The relays were mounted flush to the circuit board ground plane without the relay header soldered to the ground plane.
