  • Reduce test system set up costs with the long switching life
  • Minimize cross-talk with exceptionally high port-to-port isolation of > 80 dB
  • Optimize your system dynamic range with low insertion loss switches, 2.5 dB at 4 GHz, SP4T

Description

The Keysight Technologies, Inc. P940xA/C absorptive solid state switches, based on PIN diode technology, provide superior performance in terms of isolation, insertion loss and return loss across a broad operating frequency range. The P940xA/C are particularly suitable for high-speed RF and microwave switching applications in instrumentation, communication, radar, switch matrices as well as many other test systems.

The P9402A/C switches have a SPDT PIN diode individual control switch IC and discrete shunt pin diodes on the RF path. The discrete shunt pin diodes enhance the isolation between ports. The switch’s individual control pin controls the port between the ON and OFF state. With these features, the switch provides good port match even when it is off. Hence, this SPDT switch has three switching states, switching between the common port and port 1 or port 2 or all ports Off.

The P9404A/C switches have a SP4T PIN diode switch IC and discrete shunt pin diodes on the RF path. The P9404A/C SP4T switches have five switching states, switching between the common port to any one of the 4 output ports or, all ports to the OFF state (terminated at 50 Ohm).

Application

Solid state switches can be used in a large number of applications, increasing system flexibility and simplifying system design. They are preferred in test systems where speed is critical.

The figure above shows a typical test setup for filter bank testing. Two SP4T absorptive PIN switches are needed for the S parameter measurement with ENA. Mobile handset and semiconductor manufacturers use PIN switches because fast switching speeds are needed for high volume testing of filters e.g. SAW filters. P940xA/C are particularly suitable for the application due to two reasons; the low insertion loss optimizes the dynamic range, and TTL control enables the switches to be controlled easily, using +5V or 0V.
