We report the first generation of GaN MMIC circuits that are based on the latest generation of (ft > 320 GHz and fmax > 580 GHz) [1] GaN Transistors. The reported broadband Ka-band (27 GHz - 40 GHz) GaN LNA MMIC's have Noise Figure (NF) as low as 1 dB measured at a frequency of 37 GHz, NF < 2 dB with >24dB of gain across 28 GHz- 39.2 GHz frequency range, and a very broad range of usable...
This paper presents the first analysis on the energy efficiency of LT codes with Non-Coherent M-ary Frequency Shift Keying (NC-MFSK), known as green modulation, in a proactive Wireless Sensor Network (WSN) over Rayleigh flat-fading channels with path-loss. The current analysis is based on realistic parameters in the IEEE 802.15.4 standard including the effect of channel bandwidth and active mode duration...
