DESCRIPTION

The ultraminiature RF300and 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 features:

• High repeatability

• Broader bandwidth

• Metal enclosure for EMI shielding

• High isolation between control and signal paths

• High resistance to ESD

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.
