TO-5 RF Relay - RF300 and RF303/GRF303 Series


The TO-5 RF300 repeatable RF relay, along with the RF303 and GRF303 sensitive repeatable RF relays are ultra-miniature, hermetically sealed with DPDT contact configurations designed to provide improved RF signal repeatability over the frequency range with excellent signal integrity up to 10Gbps.
The through hole mount RF303 (stock numbers 758-2521 and 758-2518) and the surface mount GRF303 (stock numbers 758-2483) are sensitive coil versions of the through hole mount RF300 (stock numbers 399-9436 and 399-9442), they have twice the coil resistance of the standard version so require half the power to operate.
The RF300 (399-9436 and 399-9442) has a 6.99mm profile height, the RF303 (758-2521 and 758-2518) has a 9.78mm profile and the GRF303 (758-2483 and 758-2489) has a 10.6mm profile height.
The surface mount GRF303 TO-5 relays feature a unique ground shield that isolates and shields each lead to ensure excellent contact-to-contact and pole- to-pole isolation. This ground shield provides a ground interface that results in improved high frequency performance as well as parametric repeatability.
These TO-5 relays are designed for use in RF attenuator switching, wireless LAN and many other applications that require dependable high performance in which high speed signals must be transferred.

Broad bandwidth, excellent signal integrity up to 10Gbps
Hermetically sealed
Gold plated contacts
Metal enclosure for EMI shielding with high resistance to ESD
High isolation between control and signal paths
Excellent resistance to shock and vibration
High reliability and excellent resistance to environmental extremes
Uni-frame design provides high magnetic efficiency and mechanical rigidity

Note

RF300 and RF303 are through hole mount, GRF303 is a surface mount TO-5 relay.
