Product Details

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.

Design Tools


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
