Functional Diagram
General Description
The HMC496LP3 & HMC496LP3E are low noise
Wideband Direct Quadrature Modulator RFICs
which are ideal for digital modulation applications
from 4.0 - 7.0 GHz including; WLL, U-NII, WLAN &
microwave radios. Housed in a compact 3x3 mm
(LP3) SMT QFN package, the RFIC requires minimal
ex-ternal components & provides a low cost alternative
to more complicated double upconversion architec-
tures. The RF output port is matched to 50 Ohms with
no external components. The LO requires -3 to +6
dBm and can be driven in either differential or single-
ended mode while the Baseband inputs will support
modulation inputs from DC - 250 MHz typical. This
device is optimized for a supply voltage of +3.0V@
93 mA and will provide stable performance over a
+2.7V to +3.3V range.
