Small form-factor dual-balanced receiver for 40G DQPSK applications with 60% reduced footprint compared to deployed solutions is presented. High dynamic range of 10dB, high overload power, and very sensitive peak detectors (>400mV/30°) for demodulator control are demonstrated in 44.6Gb/s experiment.
