General Description

The MPD-0108BH is a 2-way Wilkinson power divider/combiner covering 1 to 8 GHz, designed using passive GaAs MMIC technology for consistent performance across a multi-octave frequency range. It delivers 1.1 dB excess insertion loss and 23 dB isolation between outputs across the full band. The device also maintains tight 0.1 dB amplitude balance and 0.8º phase balance with excellent match on all ports. For accurate simulations, use the provided S3P file taken from measured production units. The MPD-0108BH is packaged in a small form-factor 1.1 x 0.8 inch high-performance connectorized housing for easy integration into test setups and system signal paths.
