Pasternack Releases Ultra-Broadband and Millimeter Wave Low Noise Amplifiers
Pasternack, a US manufacturer and supplier of RF, microwave and millimeter wave products, has launched a new line of ultra-broadband and millimeter wave low noise amplifiers (LNAs).
These new high frequency LNAs offer very low noise figure levels, typically between 2.5 and 3dB across the entire band, making them perfectly suited for use in applications such as electronic warfare, instrumentation, fibre optic communication systems, military communications, radar, SATCOM, point-to-point radio links, telecom and R&D.
"We are continually expanding our lines of off-the-shelf RF amplifiers to meet the needs of our customers and current market trends," explains Tim Galla, Active RF Components Product Manager at Pasternack. "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."
Pasternack's newest 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 2.92mm connectors and some packages are hermetically sealed with field replaceable connectors, making these units very durable and able to withstand harsh environmental conditions. The 2.92mm connectorised models operate to 40GHz.
The new ultra-broadband and millimeter wave LNAs have IP3 levels as high as +42dBm, low VSWR and 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 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 -20degC to +70degC.
