The MILMEGA amplifiers are an important addition to the TESEQ range of EMC testing instrumentation. The new amplifiers are highly cost-effective for EMC duties, communication and other applications, and limit the cost of maintaining or upgrading, an amplifier during its service life. MILMEGA amplifiers cover the spectrum from 80 MHz to 8 GHz, and power outputs to 1000 watts. System level partitioning decisions can therefore be confidently implemented following system requirement analysis. MILMEGA employs the Corporate Amplifier Structure (CSA) topology to deliver technical superiority coupled with class leading reliability and a simple upgrade path. MILMEGA broadband Class A solid-state amplifiers deliver the required power in a package, which is half the size and weight of most amplifiers in a similar power rating range. Superior P1dB specifications provide significantly improved $/watt ratios and first class harmonic and spurious rejection specifications make MILMEGA amplifiers highly suitable for microwave applications.

Instruments For Industry (IFI) designs and manufactures a large array of RF microwave high power, RF microwave medium power and RF microwave low power amplifiers in broadband, wide-band and standard frequency bandwidths. The field of applications includes EMC, EW, laboratory and EMI testing applications. RF amplifiers types include: TWT (travelling wave tube) amplifiers, tetrode tube amplifiers, solid-state amplifiers, CW, pulse TWTA and millimetre amplifiers.

Teseq has released a new Class A RF High Power Amplifier, the CBA 1G-275. The new CBA 1G-275 broadband, 275 watt, 56 dB gain amplifier operates in the bandwidth from 80 MHz to 1 GHz. It packs more punch with an additional 25 watts output compared to its predecessor and is smaller in size 6U case (19 inch), and 550 mm deep compared to the 10U high CBA 1G-250 it replaces. The Teseq amplifier uses high reliability gallium arsenide semiconductor technology to provide low distortion linear performance across the frequency range. Typically harmonics are below 20 dBc.
This is particularly important as antennas generally have lower gains at low frequency thus requiring increased power. The Teseq CBA 1G-275 amplifier is specifically designed for operation under mismatch conditions even when faced with open circuit or short circuit conditions.
The gallium arsenide technology employed in the Teseq amplifier overcomes the relatively low compression characteristics and low efficiency associated with silicon amplifier components. The typical compression ratio 2 dB data is provided as specified by IEC 61000-4-3.
