Digital phase shifter has a minimum phase range of 360 degrees
RFMW , Ltd. announces application and sales support for the Telemakus TEP4000-5 digital phase shifter. This laboratory quality phase shifter has a minimum phase range of 360 degrees with 12-bit, 0.25 degree resolution and operates over the bandwidth of 2 to 4GHz. Maximum RF input for linear operation is +6dBm but the device can handle up to +20dBm. Typical insertion loss through the TEP4000-5 is only 5dB. When coupled with the TEA4000-7 USB controlled RF attenuator, a gain and phase control system can be created. Applications include phased array antenna testing. Weighing less than an ounce each, Telemakus test devices represent the latest technology in low cost, transportable test equipment. Each unit’s graphical user interface (GUI) is resident in on-board Flash memory making them “plug and play” for Windows-based PCs. The Telemakus TEP8000-6 is a complementary digital phase shifter spanning 4-8GHz for higher frequency applications.
