DESCRIPTION

The ultraminiature GRF121A /GRF121AR relay is a

Bidirectional, Open Contact SPDT Relay, designed

to provide a practical surface-mount switching solution

with RF performance and repeatability to 16GHz.

The GRF121A/GRF121AR improves on Teledyne

Relays’ heritage of miniature RF relays by incorporating

a precision transmission line structure in the

internal construction of the contact system. GRF121A

/GRF121AR relays feature a unique ground shield to

facilitate surface mounting and to extend the frequency

range when compared to through-hole solutions.

These relays are designed for use in RF attenuators,

RF switch matrices, high frequency spread

spectrum radios, ATE, and other applications that

require dependable high frequency signal fidelity

and performance. The magnetic-latching GRF121A /

GRF121AR is suitable for applications where power

budget is restricted. The relays can be operated with a

short duration pulse. After the contacts have transferred,

no external holding power is required.

The GRF121A /GRF121AR features:

• High Repeatability

• Wide Bandwidth Performance

• Metal Enclosure for EMI Shielding

• High Isolation Between Control and Signal Paths

• High Resistance to ESD

The unique construction features and manufacturing

techniques provide excellent robustness for

environmental extremes and overall reliability:

• 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

• Hermetic Seal

• RoHS Compliant
