High performance and cost effective HF3S and HF6 electromechanical relays benefit from a small package (15 x 7.6 x 10.6mm) and feature coil voltages of 3, 4.5, 5, 6, 9 12 and 24 Vdc. All HF series relays are SMT pad compatible and suitable for all SMD soldering processes, which enables optimum integration in high-frequency switching circuits.
Compared with alternative solutions, such as FETs or pin diodes, electromechanical high-frequency relays possess better high-frequency characteristics with better isolation and lower insertion loss. They permit the transmission of DC, AC and high-frequency signals with constant characteristics over the entire temperature range from -55°C to +85°C. The metallic contact in the closed condition permits an unrivalled low insertion loss with no signal distortion from non-linearities in the signal path. This allows the interference-free transmission of signals of high-frequency and high power.
Technical details of the new HF3 S and HF 6 relays include a single pole changeover (1formC, SPDT) and a polarized coil with low power consumption (non latching (monostable) – 140mW and latching (bistable) 1coil – 70mW and 2 coils – 140mW). Both HF3 S and HF6 devices benefit from excellent switching characteristics of 60W DC / 62.5VA AC load or 50W RF load. RF power capability is up to 150W for HF3 S components and 50W at 2.4GHz for HF6 relays. Insertion loss is very low at 0.08dB at 1GHz for HF3 S devices and 0.2 dB at 5GHz for HF6 components.
