Spirent Vertex® High Frequency Converter
Data Sheet
Enabling Channel Emulation for 5G Applications
Available in Two Congurations
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.
4-channel unit addresses entry
level (2x2 bidirectional) tests in multiple models to accommodate different
frequency ranges
20-channel unit has an internal combiner for multi-Vertex instrument
applications: stackable from 16x4 bi-directional (2 Vertex + 1 HFC) to 64x4
bidirectional (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 (Figure 2).
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
Supports internal or external
local oscillator (LO)
