- A narrow-band preamplifier for fiber-optic millimeter-wave wireless system is presented based on a fully stabilized 0.12 μm pseudomorphic high electron mobility transistor (PHEMT) technology and is realized in a Low-Temperature Co-fired (LTCC) technology. The preamplifier is designed with parallel feedback and T-section matching networks. These networks are used for narrow-band filtering function and for unconditionally stable of circuits. The preamplifier module, in corporation of four amplifying stages, shows measured transimpedance gain of 53 dB廓 and return loss of less than -10 dB with a 1 dB廓. ripple around the center frequency. The transimpedance gain difference between bare chip and module is about 3.5 dB廓. © 2006 EuMA.
