PERFORMANCE FEATURES
The ultraminiature RF300 and RF303 relays are designed to provide improved
RF signal repeatability over the frequency range. 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.
