Enabling Channel Emulation for 5G Applications

The Vertex® High Frequency Converter (HFC) was developed to bring advanced channel emulation test capabilities to 5G applications by extending the Vertex channel emulator frequency range from Radio Frequency (RF) bands to higher mmWave frequency bands. Depending on the model, the Vertex HFC converts RF ranges between 0.75GHz and 6GHz to mmWave (mmW) ranges between 5.9GHz and 40.5GHz and vice versa, allowing channel characteristic simulation in millimeter band scenarios required for 5G implementation. It can also be customized to support other mmW frequencies.

Key Features

  • Supports basic 2x2 MIMO or massive MIMO applications at mmW bands+
  • Five models to accommodate different conversion ranges and capacities
  • Supports internal or external local oscillator (LO)

 

Available in Two Configurations

The Vertex HFC is available in  two options to best suit the application; for smaller capacity implementations, the streamlined instrument accommodates up to 4 channels while the high capacity version accommodates up to 20.

  • das 4-Kanal-Gerät eignet sich für Entry-Level-Tests (2x2 bidirektional), und wird in mehreren Modellen angeboten, um unterschiedliche Frequenzbereiche zu berücksichtigen
  • das 20-Kanal-Gerät verfügt über einen internen Combiner für Multi-Vertex-Gerät Anwendungen: kombinierbar von 16x4 bidirektional (2 Vertex + 1 HFC) bis 64x4 bidirektional (8 Vertex + 4 HFC)

 

Typical Application Scenarios

The Vertex HFC can be used to inject RF channel emulation between a mmW band eNodeB (eNB) and mmW band device (Figure 1). Other scenarios include upconverting from an RF band network emulator or eNB to a mmW band device.
