Balanced Amplifiers

This ZRL series of medium power amplifiers has been enhanced as a result of the company’s Blue Cell technology that allows the use of its 90° splitters. The foremost advantage is the improvement of both input and output return loss due to reflections canceling in the hybrid couplers. Amplifier design stability is also more predictable due to each active device being terminated in a 50 Ω load. Output power and third-order intercept performance is twice that of a single device amplifier. If one half of a balanced amplifier fails, it will still operate with a gain reduction of about 6 dB.

High Power Amplifiers

This redesigned family of 20 to 1000 MHz power amplifiers offers significant improvements in performance and manufacturing. Typical of the improved value is model 5125, which has an output power of 70 W over the frequency range of 20 to 1000 MHz. The previous model’s output power was 40 W. Additionally, improved manufacturing methodology has resulted in even greater value by allowing the price to be reduced by 5 percent. This is a result of incorporating the latest technology and improving manufacturing processes. Key applications for this frequency range are EMC testing, signal intelligence and jamming.

This Celerity CS35000 series is a broadband signal analyzer (BSA) and recorder family that is designed to capture, analyze and record high speed broadband signals. For design and testing of analog or digital broadband signals or signal environments, the CS35000 series BSA offers a unique single-instrument approach for performing simultaneous measurements of frequency, time and multiple demodulation parameters. The series encompasses the test capabilities of a spectrum analyzer, deep memory logic analyzer, oscilloscope and signal analyzer — all in one instrument. All signals are displayed in one convenient window where the user can monitor up to 12 displays at one, all updating in real time. Additional features include: analyze communications and radar signals with instantaneous bandwidths up to 600 MHz and hop rates to 500,000 hops per second, captures up to 10 seconds of full bandwidth signals for detailed review, analysis and storage. Price range: $65,000 to $350,000.

Module Test System

The Seven.Five™ navigator is a dual calling-module system with inertial navigation built in providing accurate in-building wireless test. The Seven.Five navigator is lightweight, portable and battery powered, making it perfectly suited for evaluating network performance in-building or where pedestrian use is predominant. The navigator provides a level of QoS measurement in any location where cellular and Internet access is important, even if GPS positioning cannot be used. The navigation system uses a combination of silicon gyroscopes and accelerometers to measure the operator’s stride, which determines the velocity vector. The axial rotation is also measured to determine the directional vector. The system automatically plots all cellular parameters with no need for operator intervention to identify his/her location. Price: $20,000. Delivery: six to eight weeks.

RF Test Fixture

The model TS7110 is a shielded RF test fixture that is intended to simplify complicated test sequences when testing wireless modules or instruments with radio interfaces. This model is elevated in its design and mechanical expansions, which make it possible to integrate additional cameras or other sensors. This allows display tests to be possible in addition to RF, electrical and mechanical tests. The entire test spectrum for wireless instruments and modules, including functional check, can thus be concentrated in a single test fixture, drastically reducing the amount of work required for adapting the DUTs.
