Compact W-band receiver module on hybrid liquid crystal polymer board

Low cost, high-resolution and wideband millimeter wave receiver systems attain more and more attention for commercial and military applications. We present a broadband receiver module operating in the W-band for radar and imaging applications. Its compact packaging compared to traditional split block technique is realized using printed circuit board technology and a high density polyethylene lens. We present receiver architectures based on our in-house 100 nm mHEMT technology with different performances regarding the bandwidth including low noise amplifier, IQ-mixer and frequency multiplier. Measurements of the conversion gain have been performed demonstrating a bandwidth of up to 30 GHz which corresponds to a relative bandwidth of almost 33 %.
