This example describes a more developed 28 GHz antenna array capable of forming multiple beams for use in applications such as 5G network base stations. The system consists of three parts: a Rotman lens beamformer with seven input ports and eight output ports, a series of stripline Wilkinson power dividers to split each Rotman output into eight equal signals, and an 8x8 patch antenna array. The design process consists of three separate stages. This example will describe the creation of each stage of the device and evaluate the performance of the individual stages and the full device.
GORE offers an array of space cables with specialized insulation materials wo ensure that power is delivered safely and reliably in the challenging environmental conditions of outer space.
This line of iso-dividers features a light weight, small size, broadband coverage, low insertion loss, extremely high isolation, and are space qualified. They’ve been designed to provide a satellite receiver or transmitter to share antennas in a redundant configuration.
UHF Line of Sight antenna operates in the 225 to 400 MHz frequency range and is used to communicate with satellites with a low horizon orientation or with ground based signals. It’s ideal for SOTM (SATCOM-On-The-Move) operations. Its power handling at high angle is 200 Watt CW, and low angle in 100 Watts CW. Airborne and ground transceivers that accept 50 ohm antenna impedance and most tactical Multi-Band, Multi-Mode Receivers can be used in conjunction with the ARA-0548 antenna.
EMI regulations are in place to provide users with improved reliability and safety for users of electrical and electronic equipment. It is common today to perform pre-compliance measurements during the design and prototyping stages to identify and address potential EMI issues before the product is sent out for compliance testing. This application note provides an overview of EMI compliance testing, pre-compliance testing, and the measurement regulations, and presents test setups using the RSA306 and similar low cost products are used to perform both radiated and conducted emission measurements that can help minimize both the expense and schedule for getting products EMI certified.
Rohde & Schwarz’s R&S FSWP phase noise tester can measure the spectral purity of signal sources such as generators, synthesizers and voltage-controlled oscillators (VCO) more quickly than with any other solution. The high-end instrument covers a frequency range up to 50 GHz and offers a top dynamic range. It features an extremely low phase noise of its local oscillator coupled with cross-correlation that makes it possible to easily measure signal sources that in the past required complex test setups or could not be measured at all.

The R&S FSV3000 is designed to help users set up complex measurements in the simplest and fastest way possible. The R&S®FSV3000 features functions that make complex measurements fast and easy. Setting up RF parameters with touchscreen gestures is as easy as using your smartphone. The auto set feature automatically sets the most important parameters such as frequency, level and gating.
The R&S FSV3000 is designed to help users set up complex measurements in the simplest and fastest way possible. With its easy usability and high measurement speed, it is the right instrument for labs and production lines. It provides up to 200 MHz analysis bandwidth – enough to capture and analyze, for example, two 5G NR carriers at once.
The LT8609S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator designed to consume only 1.7 µA of non-switching quiescent current. The LT8609S can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers which require high transient loads.
