Solutions are available within a large variety of application areas like telecommunications, radar and CNI, satellite and groundcommunication systems, base station and mobile unit software conformance verification, signal analysis, cable modem and VoIP testing, production test systems and precision microwave related test instruments.

 If your appliication area has a partial or full match with the topics below, we can help you with the development of a customized RF solution for your application:

    • Switch Matrices
    • Complex RF Distribution Networks
    • Attenuation Matrices & Multi-Channel Subsystems
    • RF Translators
    • Mobile Unit (Radio & WLAN) Fading Simulators
    • Cellular & PCS Subsystems with Low IM Performance
    • Cable Modem Redundant Switches and Test Systems
    • Programmable Attenuators with Built-In Digital Interface
    • Custom Module and Mechanical Applications

With the above topics a wide range of RF application can be covered. Some examples of these custom solutions are mentioned in the paragraphs below in order to give you an ideea of the flexibility in sub-systems and application area's.

    Attenuation Matrices

  • Numerous versions of Attenuation Matrices for various applications have been designed and manufactured for customers. These units have typically been built in configurations that include 2x6,3x6, 4x6, 6x6, 4x4, 4x8 and 8x8 configurations. For the typical UMTS, CDMA 2000, and GSM bands the units can operate over 800 -3 GHz frequency range. However multiple units have been built for other applications and span the frequency range of DC to 18 GHz in multiple sub-band configurations.

  • Switch Matrices

  • Aeroflex-Weinschel designs and manufactures for you custom switch matrices. These matrices consist of 50Ω and 75Ω designs with high isolation and gain flatness being critical performance parameters within our designs. Designs are constructed using coaxial components for high frequency microwave applications, GaAs MMIC Switching design for fast switching applications and surface mount board designs for lower frequency, high density applications.

  • WLAN System simulator

  • This specialized subsystem is used to simulate the connectivity between a mobile unit running along a line of 3 base stations spaced from 250 to 1000 meters apart. The test subsystem is able to simulate the variation of the RF signal from the base stations reaching the mobile (as well as the signal from the mobile reaching the base stations) when the mobile is moving at speeds of up to 250 km/h. Serveral variations of this have been developed and produced. The simulator attenuates the simulated Base Station signal through three independent attenuators, then combines the signals. Each attenuator has a dynamic range of 60 dB in 1 dB steps. The operation of the unit is via a RS232 interface, ASCII commands can input parameters into the controller. Upon receiving a trigger the controller executes the program to simulate the link loss to all three Base station
