      SSPA (Solid State Power Amplifier) is an RF amplifier comprising a series of combined FET (field effect transmitter) that amplify the RF signals. These are made up of semiconductor devices such as Gallium Nitride (GaN) or Gallium Arsenide (GaAs) which provides higher performance because of their high band gaps and electron mobility at high frequencies. AmpliVisionS provide broadband and band specific, high power amplifier solutions to system designers and end customers who build on the performance of our units for their own solutions in electronic warfare,  communications, radar / avionics, EMC and product testing.  
      You can find a wide range of product line divided into a multitude of series on the basis of frequency on our website. AmpliVisionS offers standard amplifier products in bands from 1MHz to 40GHz in common use and output power from a few watts to Kilo watts. Leveraging ”building block” combinations of these documented solutions and the extensive experience of our R&D team, we react swiftly to new requirements and to offer a variety of cost-effective, value-added solutions.
      AmpliVisionS solid state amplifiers include either Gallium Arsenide (GaAs) or Gallium Nitrate (GaN) active devices: these are the devices that do the actual amplification. Simplistically GaAs has the best linearity and GaN the best efficiency.
      Applications are numerous; our focus is typically RF high power generation for RF and Microwave applications such as radio transmitter for Active Phased Array Radar System (APAR), Special communication system, Electromagnetic interference system.
      A power amplifier is designed to increase the power available to a load. Power amplifier circuits (output stages) are classified as A, B, AB and C and class D and E for switching designs. The power amplifier classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current. The angle of flow is closely related to the amplifier power efficiency.
      For our Microwave amplifiers we focus on Solid-state devices such as GaAs FETs, LDMOS, Gallium Nitrate (GaN) IMFETS and others.

      Amplifiers are specified mainly by their frequency coverage, output power, modulation types(CW, pulse or others). All amplifiers have gain, a multiplication factor that relates the magnitude of the output signal to the input signal. Typically expressed as output power to input power (power gain) is most often expressed in decibels (dB)The gain may also be specified as the ratio of output voltage to input voltage (voltage gain). Amplifier power gain depends on the source and load impedances.

      You can pick them on the basis of their frequency range, rated output power, gain at rated power, impedance, input connectors (male or female), operating and non-operating temperature, Input & Output VSWR (Voltage Standing Wave Ratio), cooling system, Modulation (Am, FM, Pulse), and Configuration (such as Rack Mount), etc.

      Always buy SSPA Amplifiers and check the detailed description of the product given in a data sheet PDF file. It helps you to ensure that you are placing an order for the right SSPA. In case of any confusion or if you don’t find the features you need, you should contact the sales team.
