Overview
The HMC496LP3E is a low noise, wideband direct quadrature modulator RFIC (Radio Frequency Integrated Circuit) designed by Analog Devices Inc. This device is optimized for digital modulation applications across a frequency range of 4 to 7 GHz. It is housed in a compact 3x3 mm QFN (Quad Flat No-Lead) SMT (Surface Mount Technology) package, making it a low-cost alternative to more complex double upconversion architectures. The HMC496LP3E requires minimal external components and provides stable performance over a supply voltage range of +2.7V to +3.3V.
