Saelig Introduces Digital Phase Shifter USB RF Modules
for Economical Configurable RF Test Measurements
Telemakus USB RF modules can be easily controlled with any Windows with the simple GUI provided to custom-create economical RF testgear

Fairport, NY: Saelig Company, Inc. announces the availability of the Telemakus TEP2000-4 and TEP4000-5 Digital Phase Shifters - the smallest USB microwave phase shifters available and priced significantly below other market offerings. These laboratory quality phase shifters have a minimum phase range of 360 degrees (400 degrees typical) with 12-bit, 0.25 degree resolution. The TEP2000-4 operates over the bandwidth of 1 to 2GHz and the TEP4000-5 operates from 2 to 4GHz. Maximum RF input for linear operation is +6dBm but the devices can handle up to +20dBm. Typical insertion loss is only 4 to 6dB. The phase shifters contain 0.5GB of flash memory used for installation files, test data, drivers, documentation, and user defined information.  These new shifters join the already-available TEP8000-6, which spans the 4 to 8GHz range for higher frequency applications.

When coupled with the Telemakus TEA4000-7 RF Attenuator, a complete PC-controlled gain and phase control system can be created.  Telemakus USB RF modules can be easily controlled with any Windows XP, 7 or 8 PC via USB with the simple included GUI.   A software API is also provided so that the modules can also be built into a LabView-based test setup.

Applications for Telemakus modules include phased array antenna testing and other RF equipment testing. Weighing less than an ounce each, Telemakus test devices represent the latest technology in low cost, portable test equipment, and can be easily transported with a laptop for RF equipment field servicing. Each unit’s graphical user interface (GUI) is resident in on-board flash memory making them “plug and play” for Window’s based PCs. Two complementary Telemakus phase shifters are available, the TEP4000-5 spanning 2-4GHz.

Multiple TelemakusUSB  RF modules can be connected and controlled to build up a complex system of RF functions that include switches, attenuators, amplifiers, signal generators, vector modulators, phase shifters, frequency doublers, and power detectors at a fraction of the cost of benchtop equipment.
