AFRACAL1-VU RF Power Amplifier

The AFRACAL1-VU is just 2U high, weighs just 8kg, and can be desktop placed, or mounted in a purposely designed rack for Base, Vehicular, Boat, and other moving Platforms.

The rack allows for rapid mount/dismount which makes it quick to install or replace in tight places.

The connectors are all in the rear for a clean front finish without the danger of cables being hooked and pulled.

The amplifier can withstand a bad VSWR and still deliver power to a partially damaged antenna to ensure communication could still be achieved during missions.

The Amplifier is fully controlled by the serial commands from the transceiver, automatically controlling the selection of low pass filter selection and PTT (TR Switches).

The Auto Sense capability will enable transceivers without serial command capability to drive the amplifier which would sense the TX frequency, select the appropriate filter, and key the PA.

The amplifier complies with MIL-STD-810G and is submersible to 1meter for 30 minutes.

The enclosure is milled from solid T6 Aluminium, etched against corrosion, and epoxy powder coated in either Military Green, Desert Tan, Sky Blue, or Navy Grey depending on the end-user application.

RF Bypass is possible whenever a Multiband HF, VHF, and UHF Transceiver are connected and the operator would dial to any frequency below 30Mhz.  The Amplifier will switch in the bypass, allowing the Transceiver Set TX power (typically 30W) to be bypassed onto an HF Dipole or rod antenna to enable HF communications.
