Description
The 778572-99 is a high-performance PXI Switch designated as the PXI-2599. This device is designed for demanding applications, featuring a 26 GHz Dual SPDT Switch. It operates efficiently within a frequency range of up to 26.5 GHz. The switch is capable of handling a maximum carry current of 1.73 Arms per channel and boasts a maximum RF carry power of 150 W at a 50 Ω load.
The minimum switch load is specified at -35 dBm, ensuring low signal loss with an insertion loss of less than 0.7 dB. The Voltage Standing Wave Ratio (VSWR) is impressively low at less than 1.7, which is indicative of its efficient signal transmission capabilities. Additionally, it features excellent open channel isolation of more than 55 dB, further enhancing its performance.
For operating conditions, the RF carry power is specified at 25 W at ≤26.5 GHz. This switch falls under the Measurement Category I, designed for measurements not directly connected to the mains. It is robust, with a surge voltage withstand capacity of 500 V. The recommended cycle speed is 5 channels per second, suitable for applications requiring rapid switching.
The contact material used is Beryllium copper, gold-plated, ensuring reliability and a long lifespan, with an expected mechanical relay life of 1 × 107 cycles. It weighs 260 g (9.2 oz.) and has dimensions of 21.6 cm × 2.0 cm × 13.0 cm, making it a compact solution with a form factor of 3U, one slot, PXI module. The device supports trigger lines ranging from 0 to 7, offering flexibility in integration and control within PXI systems.
