Distributed and lossy match active power splitters using bridged-T low-pass filter networks

Wideband active power splitters using distributed or lossy match amplification have been design and fabricated in hybrid form. These splitters use a bridged-T low-pass filter network. It provides a variable characteristic impedance without affecting the cutoff frequency and thus is powerful in application to a multiway power splitting/combining circuit which requires high impedance characteristics. A two-way distributed active power splitter has achieved a gain of 1.8+or-0.8 dB and input-output VSWRs (voltage, standing wave ratios) of less than 2:1 over 0.5 to 26.5 GHz. A two-way lossy match active power splitter has shown a loss of 1.3+or-1.1 dB and input-output VSWRs of less than 2:1 across 0.5 to 26.5 GHz.<>
