A novel Low Temperature Co-fired Ceramic (LTCC) based SoP for automotive radar applications is presented. For the first time a combination of a relatively low dielectric constant LTCC substrate and a high dielectric constant LTCC superstrate has been incorporated to enhance the overall gain of the module. The superstrate can provide additional protection to the integrated circuits (IC) in the harsh...
Nowadays antennas operated in V-band receive more and more attention as communication technology develops. Progress in material engineering opens a wide window for high frequency applications. In this paper, a broadband folded dipole antenna array is first presented, which has a magnitude of S11 lower than -10 dB over the range between 48 GHz and 64 GHz, an efficiency of 90 percent and a gain of 10...
A 53 dB gain limiting amplifier for OC-192 and 10 GbE applications is developed in a 50 GHz fT SiGe SOI complimentary bipolar process, and has 5 mV pk-pk sensitivity, 1.25 V pk-pk maximum input signal, 14 ps (20/80%) rise/fall times and 450 mV pk-pk output into matched differential 50 Ohm loads, consuming 430 mW on a 3.3 V supply. Input Cherry-Hooper gain stages limit the -3 dB bandwidth to 11 GHz...
