DESCRIPTION
The ultraminiature Series RF121/RF121R is built on
Teledyne Relays’ heritage of miniature RF relays, and
is designed to provide a compact electromechanical
switching solution with broadband RF performance
from DC to 12GHz in a leaded, hand solderable
package. The RF121/RF121R relay incorporates a
precision 50Ω transmission line in the contact system
which provides for optimum RF transmission characteristics.
The RF121/RF121R is designed for use in switchable
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 RF121/RF121R 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 RF121/RF121R features:
• High Repeatability
• Wide Bandwidth Performance
• Higher Isolation Between Each Signal Path
• 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
