SiGe Wideband Direct Quadrature Modulator, 20 - 2700 MHz

The HMC696LP4E is a low noise, high linearity Direct Quadrature Modulator RFIC which is ideal for digital modulation applications from 0.02 to 2.7 GHz including software defined radio and multi-band transmitters. Housed in a compact 4x4 mm (LP4) SMT QFN package, the RFIC requires minimal external components & provides a low cost alternative to more complicated double upconversion architectures.

The RF output port is single-ended and matched to 50 Ohms with no external components. The LO requires 0 to +10 dBm and can be driven in either differential or single-ended mode. This device is optimized for a +5V supply, and offers improved carrier feedthrough and sideband suppression characteristics. For higher frequency applications, the HMC697LP4E Direct Modulator covers 450 - 4000 MHz.
