HMC795 SiGe Wideband Direct Quadrature Modulator SMT, with VGA, 50 - 2800 MHz
The HMC795LP5E is a variable gain, direct quadrature modulator ideal for digital modulation applications from 50 - 2800 MHz including: Cellular/3G, Broadband Wireless Access and ISM circuits. Housed in a compact 5x5mm (LP5) SMT QFN package, the modulator offers a high level of integration, exceptionally low carrier feedthrough, and a low cost alternative to more complicated double upconversion architectures.
The LO requires -9 to +3 dBm and can be driven in either differential or single-ended mode. The baseband inputs will support modulation inputs from DC - 440 MHz.
The differential RF output port is driven by a 6 bit digital controlled variable gain amplifi er to nominally provide up to 32 dB of very linear gain control in 0.5 dB steps. The low carrier suppression is maintained over the VGA dynamic range. The gain control interface accepts either three wire serial input or 6 bit parallel word. In addition, the gain control can be modified through the SPI to adjust a look up table to control the gain step to as low as 0.1 dB, with reduced range, or to adjust individual gain steps for system linearization.
