HLS8-6G/UHI-TTL, Absorptive RF Switch

Our KRE-4000 series relay switching units are mainly used for the automation of EMC tests. They control the switching between the individual power amplifiers to enable a broadband measurement according to test standard without manual switching. The selection of the relays is done individually according to the customer’s requirements (frequency range up to 50 GHz possible). However, the application of the switch panels from MTS Systemtechnik is not limited to this relatively simple case. By means of examples the flexible application of this powerful device concept will be shown.

Modern radio technologies such as IoT, TETRA, Smart Metering, MIMO, Car to Car, military communication and many more require new test solutions. Not so much the frequency range, but the classic structure in mobile communication from the sender side to the receiver side was abolished. Modern communication takes place not only vertically but also horizontally. This enables a direct connection between different terminal devices without a network infrastructure. Thus, applications, products or terminal devices of this type sometimes create their own networks, expand the network or pass on information from neighbouring network subscribers.

In order to simulate such structures in a test environment, MTS Systemtechnik has developed radio field simulations of the AIAD-X+ series. The core of these consists of a fully meshed network (see figure below). This makes it possible to connect RF ports to all other RF ports via separate signal paths. Programmable attenuators in each path emulate the signal attenuation to any neighboring cells.

The AIAD-X+ devices offer a number of advantages:

• System can be adapted to specific frequencies or frequency ranges between 30 and 6000 MHz
• Arbitrary scalability from 3 to 33 HF ports
• Combinations or division of ports, e.g. Main + Diversity
• Partially meshed or unbalanced networks are also possible (e.g. only 2 adjacent cells can be addressed or only 2 ports are connected to all others)
• Adjustment of signal attenuation up to 190 dB in 1 dB steps
• Bidirectional transmission
• The systems can be designed for high input powers of up to 50W
• Outstanding isolation between ports of 165 dB
• An indirect isolation* of 75 dB (700 - 3600 MHz / 790 - 5850 MHz) could be achieved by a special circuit design.

The MX-14/6-HLS from MTS Systemtechnik GmbH is a passive full fan-out switch matrix which allows any of the 14 inputs to be routed to any or all outputs.

The operating frequency range of the switch covers 500 Mhz to 6000 Mhz. It is perfect for use in LTE and 5G test applications.

It automates test labs by replacing cumbersome patch panels and can be controlled easily via RS-232, LAN or a web control (on request) interface.

• Frequency range 500 MHz - 6000 MHz
• 14 inputs / 6 outputs
• Good VSWR 1.5 : 1 typ.
• Low insertion loss 24 dB typ.
• Ultra-high isolation 110 dB typ.
• Input power +36 dBm max.
• RS-232 and LAN interface
