SiGe WIDEBAND DIRECT

MODULATOR RFIC, 4 - 7 GHz

v05.0811

General Description

Features

Functional Diagram

the Hmc496lP3 & Hmc496lP3e are low noise

Wideband direct quadrature modulator rFics

which are ideal for digital modulation applications

from 4 - 7 GHz including; Wll, u-Nii, WlaN &

microwave radios.

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

architectures. 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 +3V @ 93 ma and will provide stable performance

over a +2.7V to +3.3V range.

Wideband rF Frequency range

High carrier suppression: 34 dBc

Very low Noise Floor: -157 dBm/Hz

low lo Power: -3 to +6 dBm

differential or single ended lo drive

single low current supply: +3.0V@ 93 ma

3 x 3 mm qFN smt Plastic Package

Typical Applications

the Hmc496lP3 / Hmc496lP3e is suitable for

various modulation systems:

• Fixed Wireless or WLL

• U-NII Radios

• 802.11a & HiperLAN WLAN

• C-band Microwave Radios
