General Description

Features

Functional Diagram

The HMC497LP4(E) is a low noise high linearity

Direct Quadrature Modulator RFIC which is ideal

for digital modulation applications from 100 - 4000

MHz

including;

Cellular/3G,

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 while the

baseband inputs will support modulation inputs from

DC - 700 MHz typical. This device is optimized for

a supply voltage of +4.5V to +5.5V and consumes

170 mA @ +5V supply.

Very Low Noise Floor: -161 dBm/Hz

Very High Linearity: +22 dBm OIP3

High Output Power: +9 dBm Output P1dB

High Modulation Accuracy

DC - 700 MHz Baseband Input

Typical Applications

The HMC497LP4(E) is ideal for:

• UMTS, GSM or CDMA Basestations

• Fixed Wireless or WLL

• ISM Transceivers, 900 & 2400 MHz

• GMSK, QPSK, QAM, SSB Modulators
