Overview
The HMC1197LP7FE is a low noise, high linearity Direct Quadrature Modulator with a Fractional-N PLL and VCO RFIC, designed by Analog Devices Inc. This component is ideal for digital modulation applications across a wide frequency range of 0.1 to 4.0 GHz. It is particularly suited for cellular, 3G, LTE, WiMAX, 4G, broadband wireless access, and ISM circuits. The device is housed in a compact 7x7 mm (LP7) SMT QFN package, requiring minimal external components and offering a cost-effective alternative to more complex double upconversion architectures.
