Ted Rappaport, founding director of NYU WIRELESS and a leading proponent of using the millimeter wave spectrum for wireless communications, discusses the FCC's recent rulemaking actions and technology developments that are paving the way to 5G.
Spacek Labs model FSP94-2 is a narrow (2 percent bandwidth) bandpass filter from its new line of FSP Series waveguide filters. Designed in WR-10 waveguide, the FSP94-2 has a passband of 2 GHz centered at 94 GHz. The lower and upper 20 dB reject points are 92 and 96 GHz respectively.
Spacek Labs model M80-5X2B is an E-band mixer covering the two radio bands of 71 to 76 GHz and 81 to 86 GHz. The mixer includes an integrated LO doubler, so that the customer need only supply a 39 GHz source with +16 dBm of power. Spacek Labs can also supply a phase-locked source with the assembly. The conversion loss over the band is 6 dB typ and 10 dB max, with an IF frequency range of 2 to 8 GHz. The input P1dB is -6 dBm typ, and the bias is +12 VDC @ 10 mA.
Used for remote sensing in various applications and environments, microwave and millimeter-wave radiometers (RM) require frequent calibration. Microwave radiometers measure noise temperature using a suitable antenna which is designed to match a scene of interest, as shown in Figure 1 . In a technical sense, if the antenna's main...
