Low-noise amps cover popular microwave bands

Endwave Defense Systems has released a new line of ultra-low-noise JCA amplifiers. With over 20 new models available to cover many of the popular microwave frequency bands, narrowband models can be optimised for sub-0.5dB noise figures over 100-200MHz subbands, with broadband multi-octave noise figure performance under 1dB maximum for C-Band frequencies and below. Higher-frequency models are available on request.

The engineering strategy to achieve this performance utilises Endwave's JCA brand amplifier building-blocks and incorporates proprietary matching techniques.

In addition to low noise characteristics, cost efficiencies have also been achieved due to minimal touch-and-tune time.

The engineering approach also results in a variety of end-use advantages.

They can be employed in either narrowband situations, such as a GPS receiver, or in an electronic surveillance system, where several octaves of bandwidth may be necessary.

As a result of their flexibility and ultralow noise performance and reliability, they are useful when system engineers are looking to improve radar sensitivity, increase dynamic range and lower reception thresholds.
