General Description
The HMC497LP4(E) is a low noise high linearity
Direct Quadrature Modulator RFIC which is ideal
for digital modulation applications from 100 - 4000
MHz including; Cellular/3G, Broadband Wireless
Access & ISM circuits. 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 -6 to +6 dBm and can be driven in
either differential or single-ended mode while the
baseband inputs will support modulation inputs from
DC - 700 MHz typical. This device is optimized for
a supply voltage of +4.5V to +5.5V and consumes
170 mA @ +5V supply.
