Broadband low noise amplifiers cover 30 MHz to 40 GHz

Pasternack has launched a line of ultra-broadband and millimeter wave low noise amplifiers that are available to ship same-day.

These high frequency LNAs offer very low noise figure levels, typically between 2.5 and 3 dB across the entire band, making them perfectly suited for use in applications such as electronic warfare, instrumentation, fiber optic communication systems, military communications, radar, SATCOM, point-to-point radio links, telecom and R&D.

The company's latest release of RF amplifiers includes 17 models covering multi-octave bandwidths with flat gain response and feature highly efficient GaAs PHEMT semiconductor technology. 50 ohm hybrid MIC circuits are enclosed in environmentally sealed metal packages with nickel or gold plating. These low noise amplifiers come with either stainless steel SMA or 2.92-mm connectors and some packages are hermetically sealed with field replaceable connectors, making them very durable and able to withstand harsh environmental conditions. The 2.92-mm connectorized models operate to 40 GHz.

The ultra-broadband and millimeter wave LNAs have IP3 levels as high as +42 dBm, low VSWR and are unconditionally stable. DC voltage supply ranges from +12 to +15 Vdc while bias current ranges from 80 mA to 1300 mA. The voltage supply is internally regulated. The broadband low noise amplifiers from Pasternack contain internal circuits including DC blocking capacitors at the RF input/output ports and are guaranteed to operate over a wide temperature swing from -20°C to +70°C.
