RF amplifiers boasting an outstanding performance that covers wide octave RF frequency bands from 9KHz to 3GHz have been introduced by Fairview Microwave. The devices are suitable for a wide variety of applications including electronic warfare, military communications, SATCOM, receivers, fibre optic communication systems, transportation systems, wireless base stations, patient monitoring systems, radio astronomy and university R&D labs.

The amplifiers exhibit exceptional noise figure levels as low as 0.5dB and high IP3 linearity up to +37dBm. The 50Ω hybrid circuits require no external matching components and are enclosed in rugged metal packages with SMA connectors making them environmentally sealed from harsh elements. Designs perform across the full operational temperature range of -40 to +85°C.

The devices have P1dB levels of up to +23, low VSWR and are unconditionally stable. Most of the amplifier designs use advanced GaAs PHEMT semiconductors for highly linear performance and high efficiency. Single DC positive voltage supply ranges from 12 to 15VDC, while bias current ranges from 40 to 190mA.

“Fairview offers a great selection of cost effective RF amplifiers which are available in-stock with same day shipment for designers who need an immediate solution for a variety of applications,” explains Brian McCutcheon, Vice President and General Manager, Fairview Microwave.
