1. Introduction

Overview

Spirent Vertex®High Frequency Converter (Vertex HFC) extends the Vertex channel

emulator frequency range from radio frequency (RF) band to higher millimeter wave

frequency (mmW) band for 5G applications. Vertex HFC converts the signal between

RF <6GHz and mmW frequency.

Two models of the Vertex HFC are available:

•4-channel model (VCE6-HFC-4C)

•20-channel model (VCE6-HFC-20C)

Vertex HFC Diagram

There is mixer on each conversion link in Vertex HFC. The RF frequency signal is

mixed with the signal from internal LO or external LO and then converted to mmW

frequency. The signal from mmW frequency is also converted to RF frequency with

the same LO. At each input/output (I/O) port, an RF and mmW filter is used to filter

out outband spurious emission or interference.

Connector Descriptions

This section describes the front panel connectors and rear panel connectors on both

models of Vertex HFC.

4-Channel Vertex HFC Connectors

The 4-channel Vertex HFC provides the following connectors on the front panel:

•mmW I/O ports (4 ports) – Connects to mmW frequency devices

•RF I/O ports (4 ports) – Connects to RF frequency devices

Figure 5. 4-Channel Vertex HFC front panel.

The 4-channel Vertex HFC provides the following connectors on the rear panel:

•LO IN port – Connects to external LO if needed

•LO OUT port – Send out LO from internal oscillator

•10MHz Ref IN – Connects to external 10MHz reference clock

NOTE:

The external 10MHz reference signal must be a CW wave signal. There will be a

frequency stability issue if the reference signal is a square wave.

20-Channel Vertex HFC Connectors

The 20-channel Vertex HFC provides the following connectors on the front panel:

•mmW I/O ports (20 ports) – Connects to mmW frequency devices

•RF I/O ports (24 ports) – Connects to RF frequency devices

Figure 7. 20-Channel Vertex HFC front panel.

The 20-channel Vertex HFC provides the following connectors on the rear panel:

•LO IN port – Connects to external LO if needed

•LO OUT port – Send out LO from internal oscillator

•10MHz Ref IN – Connects to external 10MHz reference clock

NOTE:

The external 10MHz reference signal must be a CW wave signal. There will be a

frequency stability issue if the reference signal is a square wave.
