A cylindrical hat-loaded method is employed to make monopoles behave as dual band resonators. The two frequency bands are obtained by perturbing higher propagation modes by modifying the hat length. The longer the cylindrical hat is, the lower the resonant frequencies are obtained. The hat length behaves as an inductive load, also increasing the electric(More)
A novel active load linearizer is introduced to enhance the non-linear performance of a HBT Low Noise Amplifier. This active load is configured as a Current Source. The results of this structure are compared to an equally biased non-active loaded device, obtaining a higher third order Input Intercept Point (IIP3) around 17 dBm, and a higher compression(More)
