>
The 778572-99 is a high-performance PXI Switch known by its model number PXI-2599. This particular device is a 26 GHz Dual SPDT Switch, falling under the category of RF Relay Modules. It boasts a configuration of Dual SPDT (Single Pole Double Throw), designed to handle a frequency range of up to 26.5 GHz. The switch operates with an impedance of 50 Ω, ensuring compatibility with standard RF systems.
With regards to its electrical characteristics, the switch supports a maximum carry current per channel of 1.73 Arms and can handle a maximum RF carry power of 150 W when connected to a 50 Ω load. It is designed to work with a minimum switch load of -35 dBm. The insertion loss is impressively low, at less than 0.7 dB, and the voltage standing wave ratio (VSWR) is also kept minimal, below 1.7. This switch guarantees excellent open channel isolation of greater than 55 dB, enhancing signal integrity for critical applications.
Specifically designed for RF applications, the switch can carry an RF power of 25 W at frequencies up to 26.5 GHz. It is classified under Measurement Category I, with a signal voltage capacity of up to 100 V and can withstand surge voltages of up to 500 V. The recommended cycle speed for optimal performance is 5 channels/s.
The switch’s contacts are made from high-quality Beryllium copper, plated with gold for improved conductivity and resistance to corrosion. It is designed for durability, with an expected mechanical relay life of 1 × 107 cycles. This makes it a reliable choice for demanding applications. The switch weighs 260 g (9.2 oz.), making it a lightweight yet robust option for integrating into various systems.
