Pasternack's low phase noise amplifiers cover select frequency bands ranging from 1.5 to 18 GHz with residual phase noise levels as low as -180 dBc/Hz @ 10 KHz offset. Additional performance specs include small signal gain ranging from 9 to 14 dB, with typical noise figure of 5.5 dB. Psat levels for these amplifiers range from +16 to +25 dBm with Output IP3 levels as high as +34 dBm. All models feature single DC voltage supplies and input/output RF ports are internally matched for 50 ohms with DC blocking capacitors. These compact module assemblies require no external components and are available in rugged Kovar metal drop-in packages that are gold-over-nickel-plated and support field replaceable SMA connectors. All models are EAR99 and guaranteed to meet MIL-STD-883 test conditions for hermeticity and temperature cycle.

Gas Filter Correlation CO Analyzer
Model T300U
Teledyne Advanced Pollution Instrumentation
The Model T300U Trace-level CO analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. Using IR absorption with a Gas Filter Correlation Wheel, the T300U is designed to allow ultra-sensitive CO measurements while still meeting the requirements for use as a US EPA compliance analyzer.The optical bench is enclosed in a temperature controlled oven, dramatically decreasing instrument noise and drift. The objective and field mirrors in the sample cell are gold plated to maximize signal to noise performance, while a temperature-controlled Nafion dryer on the inlet minimizes water interference caused by ambient humidity changes. Periodically, the T300U seamlessly corrects its baseline by routing the sample through a heated catalytic CO scrubber. This Auto Reference function corrects zero drift and reduces the effect of interferences.
