Abstract
An integrated active microwave filter employing high-Q active inductan ce simulating circuits is presented in this paper. Heterojunction bipo lar transistor (HBT) technology is best-suited for this specific appli cation facilitating the design and giving optimum performance with low power consumption. The prototype triple-resonator filter operates at 2.32 GHz with a 300 MHz -3-dB bandwidth. The power consumption is only 25 mW drawn from a 3-V supply.
