SMART MAS amplifier series contains all the features of our very popular MAS series of continuous duty power amplifiers. However, this new SMART unit has added features such as Controlled Output Level, Amplifier Protection, Local Failure Monitoring, and Outputs for Remote Monitoring.

As with the MAS series, this unit will accept any TPL amplifier from VHF Low Band through 960 MHz. It is designed to house up to five 100 Watt vertical slide-in amplifiers in a 19" horizontal rack, while using only 7" of vertical rack space. Each amplifier has a circuit breaker/on-off switch and LED indicators, conveniently located on the front panel for DC On, RF On, as well as for VSWR, Low Power, and Over Temperature Alarms. The rear panel has discrete connectors for RF and DC.

Blind-mate D-SUB connectors are also available upon request. As an accessory, a power supply unit with the ability to house up to five power supplies is available in a 5 1/4" high by 19" wide, rack mount enclosure (MAS-PS), with an additional 5 Amps DC auxiliary terminal available per power supply to power an exciter, etc.


  • Capable of housing five 100 Watt slide-in units in a 19" rack mount configuration.

  • Accommodates all bands from 29.7 MHz to 960 MHz.

  • Feedback Controlled Output Level.

  • VSWR and Over Temperature Protection (Power Reduction).

  • Local Failure Monitoring.

  • Outputs for Remote Monitoring.

    • LED indicators for:

    • DC ON

    • RF ON

    • VSWR



  • Forced air cooling with two thermostatically controlled fans for each amplifier.

  • 100% duty cycle operation.

  • Trunking, Repeater or Base Station operation (with antenna switch relay option).

  • Front panel circuit breaker/on-off switch.

  • Power Supply modules have Power on and Fault LED indicators and 5 Amp auxiliary terminals to power an exciter, etc.

  • Cost effective design.
