  • Patent number: 11522508
    Abstract: A dual-band MMIC power amplifier and method of operation to amplify frequencies in different RF bands while only requiring input drive signals at frequencies f1 and f2 in a narrow RF input band. This allows for the use of a conventional narrowband RF IC to drive the MMIC and does not require additional circuitry (e.g., a LO) on the MMIC power amplifier. The matching network of the last amplification stage is modified to pass f1 (or a harmonic thereof), reflect f2, pass a Pth harmonic of f2 where P is 2 or 3 and to reflect any unused 1st, 2nd or 3rd order harmonics of f1 or f2 back into the MMIC. In response to an input signal at f1, the MMIC power amplifier amplifies and outputs a signal at f1 (or a harmonic thereof). In response to an input signal at f2 at sufficient RF power, the last amplification stage operates in compression such that the MMIC power amplifier generates the harmonics, selects the Pth harmonic and outputs an amplified RF signal at P*f2.
