  • Getting Started with Electronic Projects
    In this chapter, we built and tested the RF Power Meter hardware that was based on the Linear Technology LTC5582 (RMS) power detector. We also wrote some simple software to read one of the analog inputs on the BeagleBone and convert the reading to a dBm power measurement.
  • Voltage gain control of a VGA in a UWB receiver
    For instance, the signal power level of -10.3 dBm at the output of the transmitter is reduced to -74.5 dBm after it has propagated through 10- meter UWB channel. As shown in Fig. 1, the analog received signal coming from the channel goes through an RF front-end receiver and a low pass filter (LPF), which is followed by a VGA [4].

  • A fiber optic/millimeter-wave radio transmission link using HBT as direct photodetector and an optoelectronic upconverter
    Fur- thermore, both digital and analog opticaUmi1limeter-wave ra- dio systems using video FM- and a 140Mbps QPSK-subcarrier are introduced at a wavelength of 0.83 pm and RF frequency of 50 GHz band. Although the system experiments of FM video and 140 Mbps digital transmission involve short path-length transmis- sion of meter order in the transducer transmission power level of -20 dBm to -40 dBm, the links are promising for indoor applications (LAN and …
  • Implementation of a photonic antenna in optical OFDM link
    The measurements of the equivalent isotropically radiated power (EIRP) and signal to noise ratio (SNR) are done with a fixed 0 dBm RF input signal into the directly modulated laser (DML) for all the simulations. The results show that the analog optical wireless link is very suitable to carry the OFDM signals. The results have shown that, the active photonic antenna provides sufficient service for more than 30 meters .
