MACOM's MAUC-011003 is an integrated up-converter assembled in a lead-free 4mm 24-lead PQFN plastic package. This device has a typical conversion gain of 12dB, and an image rejection of 15dBc. This up-converter includes a LO doubler, LO buffer amplifier, and RF buffer amplifier. Variable gain can be achieved by adjusting the bias, with turn-down trajectories optimized to maintain linearity and 2xLO leakage over the gain control range. The output IP3 is 32dBm at maximum gain.
