Functional Diagram
General Description
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 amplifier 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.
