Noise Figure BREAKTHROUGH !!!
AmpliTech has designed a special amplifier to work in the 12-18 GHz frequency band. The amplifier is a breakthrough in amplifier technology because the noise figure is a mere 0.9 dB (overall max NF of 1.1 dB). The Noise Figure specification is very consistent across the ENTIRE bandwidth - Actual data is shown below. The APT2-12001800-1105-D2 is available in our D2 housing.

High Performance X Band LNA’s
X band amplifiers are in very popular demand because it is the main frequency band of communication for the military. One very special amplifier is the APTW3-07250775-04203-137, which is a waveguide (CPR137G) with typical noise figures in the 0.5 dB range. The frequency range is 7.25-7.75 GHz but can be extended out with minor changes. The current draw is only 45mA typ. Actual Data is shown below:

Cryogenic LNA’s
Due to the increased demand for even lower noise figures, AmpliTech has begun its design of cryogenic amplifiers. These amplifiers are designed to operate at extremely low temperatures (below the Liquid Helium temperature of 16 degrees K) in order to take advantage of the decreased noise figures at these levels.
Efficiency is key for Cryogenic amplifiers so we offer very low DC Power options (as low as +3 VDC), very low current consumption, and a very lightweight, compact housing/design. These amplifiers are very useful for applications that require the absolute lowest amounts of noise injection - such as Medical Applications, RF Imaging, Research & Development, Space Communications, Accelerators, and many other applications. Noise figures as low as 0.07 dB (<5° K) are possible at L band frequencies. These amps are extremely stable and highly reliable at these operating temperatures. Custom solutions are always an option. Cooling systems are also available for all our Cryogenic Amplifiers. Cryogenic amplifiers can be supplied with waveguide or SMA connector interfaces. Actual Data is shown below:

Space / Flight Qualified LNA’s
These Low Noise amplifiers are designed, manufactured, tested, and screened to be extremely reliable and rugged for Space or Flight Applications. We use the highest quality parts and pass them through the most rigorous testing procedures. Screening options include MIL-STD-883 and MIL-PRF-38534. In addition to the testing and standards that goes into these amps, we also provide complete documentation, Total Quality, Dedicated Project Management, Status Reporting, and the most essential requirement; Excellent Customer Service. Applications include Space Communications, Satellite applications, Flight systems, R&D, or just Hi-Rel applications that require high Mean-Time-Between-Failure numbers (as high as 1 Million hours). Custom designs are available including low cost options to meet your budget or level of necessity.

K Band SatCom LNA
AmpliTech’s latest waveguide design (Model No. APTW4-18002650-214K10-42) is a waveguide (WR-42) amplifier having an operating frequency of 18.0 – 26.5 Ghz, an ultra low noise figure of 191.3 °K typ, and a minimum output power of +10 dBm (+18 dBm typ). Smaller bandwidths are available with even better results. Its design is a two piece modular system - which helps in the assembly, troubleshooting, and field repairs of the amplifier. This model is unconditionally stable and can operate with the most intense weather conditions, temperatures (-55° to +85°C), shock, and vibrations. The amplifier comes with a 3 year standard warranty. These amps are very popular with the military, telecom, telemetry, and space applications. Actual Data is shown below:

All Purpose Wide-Band LNA
AmpliTech’s popular solution to wideband coverage is the APT4-00101800-2510-D6. The SMA connectorized LNA has an operating frequency of 0.1 – 18.0 Ghz, an ultra low noise figure of 2.5 dB max (2.1 Typ) above 0.5 GHz, a minimum output power of +10 dBm (+20 dBm IP3), a minimum gain of 26 dB, with a gain flatness across the entire band of ±2.5 dB. Very important for system integration is its VSWR, which is typically 2.0:1 for both the input and output. The amplifier comes with a 3 year standard warranty and can be modified to cover down to 0.1 GHz with minor specification changes. These are very popular for test bench applications, CW and Flat noise figure ECM systems, simulators, and as Noise Figure (or Spectrum) Analyzer pre-amps. . Actual Data is shown below:

Ultra-Linear Limiting Amplifier
AmpliTech’s latest limiting amplifier product is the APT55-02001800-5011-D6-LM. It is a connectorized (SMA) amplifier having an operating frequency of 2.0 – 18.0 GHz, very linear gain of 64 dB, and a minimum saturated output power of +16 dBm .This model is unconditionally stable and operates in the MIL Avionics environment from -55° to +85°C. It also features a two-tone performance minimum of 6dB amplitude differential for any 2 output signals in the harmonic band (that have a minimum of 6 dB amplitude differential at the input). This amplifier has become a very popular solution in DLVA’s, SDLVA’s, and IFM systems (2nd harmonic suppression), receivers, and simulators. Actual Data is shown below:

Wide-Band LNA with High Output Power
AmpliTech has engineered an all-purpose, medium power, wideband LNA to cover a wide variety of applications. The APT3-01001800-3919-D4 is a connectorized (SMA) amplifier having a minimum output power of 19.0 dBm, an operating frequency of 1.0 – 18.0 GHz, a maximum noise figure of 3.9 dB max, and a minimum gain of 24 dB with a flatness of ± 0.7 dB. The amplifier is very efficient, using only a nominal current of 330 mA (+15VDC supplied) and provided in a ultra small, lightweight package. It can be customized with a sloped or equalized gain to compensate for any system losses especially for simulators, bench testing, prototyping, and to be cascaded along with noise sources. Actual Data is shown below:

VHF/ UHF LNA with High Output Power
AmpliTech is expanding into other areas. We are looking to offer different frequencies, powers, and housings for various other applications. An example of this is our APTMP4-00100200-2527-D6.
