Functional Diagram
General Description
The HMC697LP4(E) is a low noise, high linearity Direct
Quadrature Modulator RFIC which is ideal for digital
modulation applications from 0.2 to 4.0 GHz including;
Cellular/3G, WiMAX/4G, 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. This device is optimized for a +5V
supply, and offers improved carrier feedthrough and
sideband suppression characteristics.
