RF High Switching Speed High Isolation Test Systems SP10T PIN Diode Switches

SP10T PIN Diode Switches belong to a type of multi transistor array switches. A multi transistor array switch is composed of several PIN tubes in parallel (or series) at equal intervals on a uniform transmission line. Adopting a multi transistor series connection circuit can increase the power capacity of the channel switch; The use of multi tube parallel connection can improve the isolation of the channel switch.

The main performance indicators include bandwidth, insertion loss, isolation, switching speed, voltage standing wave ratio, etc.For multi transistor switches, high isolation and wide frequency band are their advantages, but the disadvantages are the large number of tubes, high insertion loss, and difficult debugging.

The SP10T PIN Diode Switche consists of a movable end and a fixed end. The movable end is the so-called "knife", which needs to be connected to the incoming line of the power supply, that is, the end of the incoming power, usually connected to the handle of the switch; The other end is the power output end, also known as the fixed end, which is connected to the electrical equipment. Its function is: firstly, it can control the power supply to output in ten different directions, which means it can be used to control ten devices or control the same device to switch operating directions.

The SP10T PIN Diode (SP10T) switch is usually used in microwave testing systems to send various RF signals between instruments and conduct various tests using the same equipment at the same time.
