The following unique construction features and
manufacturing techniques provide excellent robustness to
environmental extremes and overall high reliability:
• Uniframe 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
• Hermetically sealed
• Solder Dipped Leads, (RoHS compliant solder option
available)
The Series RF300D/RF303D and RF300DD/RF303DD relays
have internal discrete silicon diodes for coil suppression
and polarity reversal protection. This hybrid package
reduces required PC board floor space by reducing the
number of external components needed to drive the
relay.
RF300DD Repeatable, RF relay with internal diodes for coil transient suppression and polarity reversal protection
DESCRIPTION
The ultraminiature RF300 and RF303 relays are designed to
provide improved RF signal switching repeatability over the
frequency range. These relays are engineered for use in RF
attenuator, RF switch matrices, ATE and other applications
that require dependable high frequency signal fidelity and
performance.
The RF300 and RF303 feature:
• High repeatability
• Broader bandwidth
• Metal enclosure for EMI shielding
• High isolation between control and signal paths
• High resistance to ESD

RF NOTES
1. 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 unutilized
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.
