AmpliTech Introduces New Amplifier Designs For Military Applications
Holbrook, NY -- AmpliTech Inc. recently announced a number of new amplifier designs for military and defense applications. The new designs include a line of space/flight-qualified low-noise amplifiers (LNAs), a Ka-band LNA for satellite communications, and a limiting amplifier for avionics applications.

Space/Flight-Qualified LNAs
These new LNAs are designed, manufactured, tested, and screened to be reliable and rugged for space or flight applications. For reliability, hermetically sealed Kovar housings are used. Screening options include MIL-STD-883 and MIL-PRF-38534. Specific applications include space communications, satellite, flight systems, R&D, and other high-reliability applications that require mean-time-between-failure (MTBF) numbers as high as 1 million hours. Custom designs up to 40 GHz are available, as are low-cost options.




Ka-Band Satcom LNA
AmpliTech's latest waveguide design (Model APTW4-18002650-2510-42) is a waveguide (WR-42) amplifier with an operating frequency of 18.0 to 26.5 GHz, a noise figure of 2.2 dB (191.3° K) maximum, and a minimum output power of +10 dBm (+20 dBm IP3). Optimized bandwidth from 17.8 to 21.3 GHz can also be provided with noise figure as low as 135ยบ K. The design is a two-piece modular system, which helps in the assembly, troubleshooting, and field repair of the amplifier. This model is unconditionally stable and can operate under intense weather conditions, temperatures (-55° to +85° C), shock, and vibrations. The amplifier can be modified to fit exact specifications for military, telecommunications, telemetry, or space applications.


Ultra-Linear Limiting Amplifier
AmpliTech's latest limiting amplifier product is the APT55-02001800-D66-LMS. It is a connectorized (SMA) amplifier with an operating frequency of 2.0 to 18.0 GHz, a noise figure of 2.4 dB maximum, linear gain of 64 dB, and a minimum saturated output power of +16 dBm. The amplifier is unconditionally stable and operates in the military avionics environment from -55° to +85° C. It also features a two-tone performance minimum of 6 dB amplitude differential for any two output signals in the harmonic band (that have a minimum of 6 dB amplitude differential at the input). This amplifier has applications in DLVAs (detector log video amplifiers), SDLVAs (successive detection log video amplifiers), and IFM (instantaneous frequency measurement) systems (second harmonic suppression), receivers, and simulators.
