    Co-Authors: Angel Blanco Granja, Idelfonso Tafur Monroy, Andreas Penirschke, Bruno Cimoli, Sebastian Rodriguez, Rolf Jakoby, Jesper Bevensee Jensen, Tom K. Johansen
    Abstract:

The proposed architecture combines the functionality of a balun and, simultaneously, the rectification of the input signal. The dual functionality of the Schottky diodes applied, leads to a compact configuration that, according to the authors’ knowledge, has not been shown before. The manufactured prototype is able to demodulate error free a 2.5 Gbps amplitude shift keying signal at 8 GHz carrier frequency, achieving a bitrate to frequency carrier ratio (Δb) of 31.25%.

    Co-Authors: Angel Blanco Granja, Idelfonso Tafur Monroy, Andreas Penirschke, Bruno Cimoli, Sebastian Rodriguez, Rolf Jakoby, Jesper Bevensee Jensen, Tom K. Johansen
    Abstract:

    This paper reports on an ultra-wideband (UWB) Schottky diode based balanced Envelope Detector for the L-, S-, C- and X- bands. The proposed circuit consists of a balun that splits the input signal into two 180° out of phase signals, a balanced Detector, that demodulates the two signals, a low pass filter that rejects the second harmonic spurious from the Schottky diode and a bias tee that selects the optimum rectification point. The manufactured prototype is able to demodulate error free a 4 Gbps amplitude shift keying (ASK) signal at 4 GHz carrier frequency, leading to a record bitrate to frequency carrier ratio (Δb) of 100%. Besides this, the Detector achieves error free demodulation for carrier frequencies between 4 and 8 GHz, while keeping the bitrate at 4 Gbps.

The circuit consumes 3µW from a 1.2V power supply.

    Co-Authors: Bruno Cimoli, Tom K. Johansen, Juan Sebastián Rodríguez Páez, Arsen Turhaner, Juan Jose Vegas Olmos
    Abstract:

    This paper reports on an ultra-wideband (UWB) Envelope Detector (ED) based on a high electron mobility transistor (HEMT). The ED has a single-ended architecture and consists of an input matching network, a HEMT as the rectifying element, biasing networks and a low pass filter (LPF). A prototype of the ED was manufactured in microstrip technology. Experimental results show that the ED can successfully demodulate amplitude shift keying (ASK) signals up to 2.5 Gbps at 5–9 GHz carrier frequencies. The ED achieves error free transmissions at 2.5 Gbps for 6 GHz carrier frequency, which corresponds to a bit rate to frequency carrier of 41.7%. Furthermore, the ED shows outstanding performance in terms of conversion loss, even reaching a gain of 2.5 dB at 6 GHz with a modulated signal of −15 dBm of carrier power.
