* Three-way Power Divider
This complete line of three-way power dividers is designed for wireless communication bands from 800 MHz through 2.6 GHz. The casing is less than half the size of a typical printed microstrip three-way power divider, which is achieved by the use of a multi-layer design that combines the typical in-phase power divider design with a broad side coupler design. The five component Xinger® family covers a host of frequency ranges for D-AMPS, GSM, DCS, PCS, W-CDMA, UMTS and MMDS applications. This family provides a typical insertion loss of 0.20 to 0.25 dB with input SWR better than 1.35 and 1.50 on the outputs. Amplitude balance has been optimized to ±0.2 dB with minimum isolation between outputs of minimum 20 dB.

* Antenna Performance Enhancer
The AccuWave product line is designed to improve the performance and reduce the size and cost of global positioning system (GPS) antennas for high precision applications. AccuWave employs the company's artificial magnetic conductor technology, which isolates antennas from nearby influences that could degrade performance. In the case of GPS, signals transmitted by the GPS satellites often arrive at the user via various paths; directly from the satellite, but also via bounces off the ground of from obstructions such as nearby buildings. This reduces the GPS's ability to accurately determine location. AccuWave-enhanced GPS antennas use artificial magnetic conductor (AMC) technology to filter out and greatly reduce these bounced signals. AMC creates a near perfect antenna groundplane and significantly improves the accuracy of GPS systems, which is critically important for high precision applications like surveying.

Power and frequency ranges of 2 to 500 mW and 10 to 2000 MHz make the model 7100 a perfect choice of numerous low power RF test and troubleshooting applications in product development, repair, field service and manufacturing. The ease-of-use design of the 7100 allows users to receive measurements quickly without external sensors and cabling. The large 3-1/2 digit liquid crystal display (LCD) provides easy-to-view readings in digital format.
