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
