The Model 800A3A is a self-contained, air-cooled, broadband, solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. The Model 800A3A, when used with an RF sweep generator, will provide a minimum of 800 watts of swept power.

A digital control panel provides both local and remote control of the amplifier. The display provides operational presentation of forward power and reflected power, plus control status and reports of internal amplifier status. Special features include a gain control, RF output level protection, and a transformer with selectable taps for matching to different load impedances.

All amplifier control functions and status indications are available remotely in IEEE-488, RS-232 and USB. The buss interface connectors are located on the back panel and positive control of local or remote operation is assured by a keylock on the front panel of the amplifier.

The 800A3A amplifier is intended for applications where the load impedance is not necessarily 50 ohms. The selectable output impedance provides the capability to drive loads that would otherwise cause a high SWR and limit the delivered power. The impedance matching transformer uses high-voltage/high-current vacuum relays so the user can “hot switch” between impedances without damage.

The Model 800A3A is housed in a cabinet and designed to provide complete standalone performance for RF testing. It is also configured to be used as a sub-amplifier in a 1500 watt or 5000 watt higher power amplifier. It can be added in an incremental fashion to become a part of these higher power units yet still be used as a standalone 800 watt amplifier.

 
 
     
 
 

1500A3

Model 1500A3 1500 Watts CW 10kHz–3MHz

The Model 1500A3 is a self-contained, air-cooled, broadband, solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. The Model 1500A3, when used with an RF sweep generator, will provide a minimum of 1500 watts of swept power.

The 1500A3 is part of AR’s Expandable Power concept, which gives the amplifier much more versatility. The 1500A3 consists of two 800A3 sub-amplifiers housed in a single equipment rack with a controller. The 1500A3 can function as one amplifier or be separated and operate as two separate 800A3 amplifiers which can be easily removed and used independently.

 
 
     
 
 

5000A3

Model 5000A3 5000 Watts CW 10kHz-3MHz

The Model 5000A3 is a self-contained, air-cooled, broadband, completely solid state amplifier designed for applications where instantaneous bandwidth and high gain are required. The Model 5000A3 when used with an RF sweep generator, will provide a minimum of 5000 watts of swept power.

Housed in a stylish, contemporary enclosure, the Model 5000A3 provides readily available RF power for typical applications such as component testing, watt meter calibration, particle accelerators, plasma generation, communications and use as a driver for higher power amplifiers.
