HV - 1.6MHz to 170MHz

The Afracal 2 is a DUAL Power Amplifier facilitating un-compromised communication for tactical missions through HF, VHF and UHF. Amplifier 1 covers 1.6-30 MHz at 125W and 30-88 MHz at a typical 100W. Amplifier 2 covers 30-512MHz at 50W. Each Amplifier has its own RF input which is automatically routed to the applicable PA while the outputs are switched automatically through to the correct band antenna by the antenna switch based on a priority selection with two radios connected.

With a single wideband radio connected to Radio1 ports, Amplifier 1 will provide 125W for the HF and 100W for VHF Low Band. An automatic selection of Amplifier 2 from 88MHz upwards enables 100W from 88.1MHz to 170Mhz and then 100W/75W up to 512MHz to provide seamless triple-band 1.6 – 512 MHz amplification.

Each of the 2 Amplifiers has its own RF input which is automatically routed to the applicable PA while the outputs are switched automatically through to the correct band antenna by the automatic antenna switch for HF, VHFL, VHFH+UHF based on a priority selection with two radios connected

The amplifier and low pass filters switching are controlled from the Radios and Amplifier logic to ensure seamless performance.

The Afracal 2 can also be provided in a single amplifier configuration with only HF/VHFL (1.6-88MHz) or VHF/UHF (30-512MHz)

COMPACT DESIGN

Designed to fit into tight spaces within military vehicles, the Afracal 2 amplifier is one of the most compact available. 

MIL-STD-810G

The powder-coated T6-Aluminium casing ensures compliance to MIL-STD- 810G specifications.


ATU

A rear connector facilitates communication to external high power antenna tuners converting radio RS232 to robust RS485 control signals for extended installation distances between the amplifier and the tuner.


SET-UP

Set-up is automatically controlled by the connected radio.

DISPLAY

The user-friendly display indicates the selected transmission frequency, RF output-power and VSWR is indicated on a bar graph. 

DATA

High data rates can be maintained due to the exceptional linearity. 

POWER SUPPLY

The Afracal 2 amplifier can operate from 10 - 35VDC. The connected radio is supplied with a stable 12VDC simplifying power supply configurations and reducing cabling.

INSTALLATION

Purpose built base station and vehicular mount racks are available to facilitate quick extraction, cooling and vibration damping.
