This new scheme leads to a sensitivity equivalent to that achieved at room temperature ( α min 3 × 10 –10 cm –1). The first CRDS spectrum of methane cooled down to liquid nitrogen temperature has been recorded in the region of the 1.58 μm methane transparency window, of particular ...
Silicon PIN Diodes • Current-controlled RF resistor for switching and attenuating applications • Frequency range above 10 MHz up to 6 GHz • Especially useful as antenna switch in mobile communication • Very low capacitance at zero volt reverse bias at freuencies above 1 GHz (typ. 0....
