2-way high power splitter
Power splitters are widely used in RF / microwave systems. Most manufacturers try to make their products as broadband as possible for using in a variety of applications. However, it is inevitably deteriorating other characteristics, such as insertion loss, isolation, phase and amplitude imbalance between output and input. Our company design and develops customized splitters and combiners for specific applications in order to achieve the highest possible performance. As an example, here represented power splitter for testing systems of RF power amplifiers.
4-way high power splitter
Power amplifier modules consist of several separate transistor amplifiers, the power of which is added up using combiners. Moreover, a combiner should not only withstand total power of all amplifiers, but also ensure addition of powers of all channels with equal amplitudes and certain phase relationship between channels. Different electrical lengths of channels could be due to difference between phases on each channels of input splitter, as well as different design features of power amplifier module. As an example, here represented specialized power splitter / combiner system, developed according to a design of customer’s power amplifier module. It has integrated protection systems: isolators, transition and reflection power detectors, temperature sensors, and etc.
Bandpass Cavity Filters
Bandpass cavity filters have the highest quality factor among all types of microwave filters. Due to this, we could get bandwidth only 1-2% but quite low losses. Such filters are most often used in transceiver paths, telecommunication systems, antenna units, including in phased arrays and RF beam forming modules. Cavity filters have good heat dissipation and reliable constructions, that is important for high power radiation, as well as good frequency selectivity and a slight deterioration of noise figure in receiving mode.
L band power phaseshifter
L-band phased arrays are widely used in air traffic control systems. For these arrays we offer a high power phaseshifters for standard low L-band frequency range. Peak power up to 500W and average power of 10W allows to use phaseshifter in passive radars. Standard TTL control is easy to use with any control system or FPGA. Slim waterproof package and light weight makes represented phaseshifter perfect solution for any applications where reliability is critical.
S band power phaseshifter
High power phaseshifters are widely used in passive phased arrays. Represented pin diode phaseshifter has advantages of fast switching, low insertion loss, high peak and average power. For last 4 decades pin diode phaseshifter is a typical solution for high RF power control. Our engineers are experienced in pin diode technique and have a number of successfully completed projects. The presented 6-bit 200W phaseshifter is used in a system for measuring the electric length of a power amplifiers. Manually controlled phase shift allows changing amplified signal phase with a step of 5.6 deg.
TR module controller
Automated testing systems are necessary for tuning multifunctional devices, such as transceiver modules of telecommunication systems, phased arrays and RF beam forming modules, as well as satellite communication systems. A small FPGA-based device allows a wide range of applications starts from simply switching TTL signals to generating a specific data exchange protocol with feedback and synchronous monitoring of external devices such as power supplies or vector network analyzers (VNA). As an example, here represented controller for RF TR module.
