Boosting Levels

The 2017 IMS exhibition floor will feature a “who’s who” collection of amplifier suppliers in almost every shape and size, from tiny ICs to massive rack-mount systems for military radar and electromagnetic-compatibility (EMC) testing. The requirements are also far-ranging, since emerging applications such as IoT devices require signal amplification with almost no current and power consumption, posing real design challenges for designers of amplifiers aimed at those applications.

AmpliTech (Booth 711) has long supplied some of the highest-performance amplifiers in the industry, whether for commercial or military use. Its customer list includes some of the top research facilities in the world and leading defense contractors. The company’s amplifiers feature some of the lowest noise figures in the industry, and are supplied with waveguide or coaxial connectors as needed.

For example, model APT4-18004000-4008-D20 is constructed to MIL-STD-883 and MIL-STD-45208 requirements for applications from 18 to 40 GHz using field-replaceable female SMA connectors. With typical noise figure of 3 dB and gain of 41 dB across that frequency range, it is well-suited for point-to-point radios and test-equipment applications in military and space environments. The gain stays flat within ±3 dB and the amplifier provides +12 dBm typical output power at 1-dB compression.

In contrast, at lower frequencies, AmpliTech’sAPTW6-07100840-50K10-WR112-D6 has WR112 waveguide input for X-band satellite-communications (satcom) applications from 7.1 to 8.4 GHz. To achieve maximum receiver sensitivity across those frequencies, this amplifier achieves a noise temperature of only 40 K (a noise figure of a mere 0.56 dB) with healthy typical gain of 63 dB across the full frequency range. The gain is flat within ±1 dB, with typical output power of +13.5 dBm at 1-dB compression.

The rugged, weatherproof amplifier is also a candidate for weather-radar, traffic-control, and law-enforcement applications. It includes an internal dc regulator and reverse-voltage protection to outlast even the clumsiest of handling.
