Functional Diagram
General Description
The HMC495LP3 & HMC495LP3E are low noise
Wideband Direct Quadrature Modulator RFICs which
are ideal for digital modulation applications from 250 -
3800 MHz including; Cellular/3G, Broadband Wireless
Access & ISM circuits. Housed in a compact 3x3 mm
(LP3) SMT QFN package, the RFIC requires minimal
external components & provides a low cost alternative
to more complicated double upconversion architec-
tures. The RF output port is single-ended and matched
to 50 Ohms with no external components. The LO re-
quires -6 to +6 dBm and can be driven in either dif-
ferential or single-ended mode while the Baseband in-
puts will support modulation inputs from DC - 250 MHz
typical. This device is optimized for a supply voltage of
+3.3V @ 108 mA and will provide stable performance
over a +3V to +3.6V range.
