SiGe WIDEBAND DIRECT

MODULATOR RFIC, 4.0 - 7.0 GHz

v03.0206

General Description

Features

Functional Diagram

The HMC496LP3 & HMC496LP3E are low noise

Wideband

Direct

Quadrature

Modulator

RFICs

which are ideal for digital modulation applications

from 4.0 - 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.

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
