These Power Amplifiers are designed to operate in a saturated mode while driving loads with varying amplitude and phase across broad frequency ranges. Load mismatches have a tendency to cause wide variations in output power and amplifier efficiency as the amplifier sweeps the frequency range. The "S.M.A.R.T." acronym refers to the amplifiers being designed to maximize output power for a given average DC input power as the amplifier is swept across the frequency band; specifically, the amplifier monitors input power and adjusts amplifier parameters to achieve maximum output power. Although these S.M.A.R.T. Power Amplifiers are rated for a specific maximum total input power, that power can be factory adjusted per customer request.

Spectrum Microwave Adaptive Reduction Technology

Efficient amplification is a system designer's goal and we design Linear Class A, Class AB, and custom Class C high power amplifiers with efficiency in mind. Products include both broadband, high linearity amplifiers, as well as high frequency, narrowband, higher power amplifiers to 500 watts with strict attention to size and value.

Spectrum Microwave's power amplifier solutions includes several broadband models covering 2 to 6 GHz in a small, low profile, package. Using advanced semiconductor technologies such as GaN and HEMT for broaded bandwidths, along with a number of proprietary design techniques, our power amplifiers deliver exceptional performance from 1 watt to 500 watts.

Spectrum Microwave's family of S.M.A.R.T. Power Amps are feature rich, offer wide bandwidth and highly efficient. They are also able to adapt and automatically correct for changes in both load impedances and bias fluctuations. SMI also incorporates many features not normally found in power amplifiers, including those listed below.
