Pasternack Enterprises Inc of Irvine, CA, USA (which makes passive and active RF, microwave and millimeter-wave products) has launched a line of ultra-broadband and millimeter-wave low-noise amplifiers that are in-stock and available to ship same-day. The new high-frequency LNAs offer very low noise figures, typically 2.5-3dB across the entire band, making them suitable for applications such as electronic warfare, instrumentation, fiber-optic communication systems, military communications, radar, SatCom, point-to-point radio links, telecom and R&D.
Featuring highly efficient GaAs pHEMT technology, Pasternack's newest release of RF amplifiers includes 17 models covering multi-octave bandwidths with flat gain response. The 50 ohm hybrid microwave integrated circuits (MICs) are enclosed in environmentally sealed metal packages with nickel or gold plating. The LNAs come with either stainless-steel SMA or 2.92mm connectors, and some packages are hermetically sealed with field-replaceable connectors, making them very durable and able to withstand harsh environmental conditions. The 2.92mm connectorized models operate to 40GHz.
The new ultra-broadband and millimeter-wave LNAs have IP3 levels as high as +42dBm and low VSWR (voltage standing wave ratio), and they are unconditionally stable. DC voltage supply ranges from +12 to +15Vdc, while bias current ranges from 80mA to 1300mA. The voltage supply is internally regulated. The broadband low noise amplifiers 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.
"We are continually expanding our lines of off-the-shelf RF amplifiers to meet the needs of our customers and current market trends," says Tim Galla, Active RF Components product manager. "This selection of ultra-broadband, low-noise amplifiers offers designers many options for highly linear gain and output power levels that cover a wide variety of applications for RF, microwave and millimeter-wave frequency bands."
