The PS6000L from DS Instruments is an ultra-wideband active RF Phase Shifter that operates from 0.4 to 6 GHz. This handheld stand-alone and remote controlled phase shitfer provides a phase shift from 0 to 360 degrees in 1/2 degree steps. It can be controlled via the front panel on the device or via a USB port.
The phase shifter has a NO insertion loss (internal limiter & amplifier) and can accept an input power range from -15 to 10 dBm. It is available in an ultra-compact powder-coated aluminum benchtop case and is ideal for antenna systems, beam forming research, MIMO, LTE and WiFi applications.
