London — The range of Axicom RF relays from Tyco Electronics has been extended to include a shielded 3 GHz relay and a 6 GHz relay to address the market requirements of increased frequency switching of analogue signals and transmission rates of digital signals. New HF3S and HF6 are developments of the well established HF3 relay and have been designed for 50 ohm or 75 ohm impedance applications and a frequency range of 200 MHz up to 6 GHz.
High performance and cost effective HF3S and HF6 electromechanical relays benefit from a small package (15- x 7.6- x 10.6-mm) 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 to +85 degrees Celsius. 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.
Both HF3 S and HF6 devices benefit from excellent switching characteristics of 60 W DC/62.5-VA AC load or 50 W RF load. RF power capability is up to 150 W for HF3 S components and 50 W at 2.4 GHz for HF6 relays. Insertion loss is very low at 0.08 dB at 1 GHz for HF3 S devices and 0.2 dB at 5 GHz for HF6 components.
