High-frequency (RF) relays switch radio-frequency signals with minimal insertion loss and excellent impedance matching — essential for test and measurement equipment, RF switching matrices, communications systems, and radar equipment operating from DC to 18 GHz+. Our RF relay inventory covers coaxial relays, surface-mount RF relays, and PCB-mount RF switches from Teledyne Relays (RF300/RF310 series), Coto Technology (RF reed relays), Omron (G6K-RF series), and Panasonic (TQ series) — with frequency ranges from DC to 3GHz, 6GHz, and 18GHz+, impedance matching at 50Ω or 75Ω, and insertion loss as low as 0.1dB at 1GHz.
High-frequency RF relays (> 6 GHz) for 5G test equipment and high-isolation (>80dB) relays for spectrum analyzers are frequently subject to long lead times or controlled distribution. Welllinkchips stocks standard RF relay types and can source hard-to-find high-frequency or high-isolation relays for repairs to legacy test equipment.
