The ARS1012 is a miniature 75O microwave relay designed for high-frequency RF switching applications operating up to 3 GHz. It features a single-side stable contact configuration with a 12 V DC nominal coil voltage and standard PC board terminal mounting. The relay exhibits excellent high-frequency characteristics with a maximum VSWR of 1.40 at 3 GHz, insertion loss of 0.30 dB maximum, and isolation of 35 dB minimum at 3 GHz. With a super-miniature form factor of 14 × 8.6 × 7.2 mm, the ARS1012 provides a 60% volume reduction compared to RK relays, making it ideal for space-constrained RF and microwave applications including telecommunications, test equipment, and signal routing systems.
