SiGe WIDEBAND DIRECT
MODULATOR RFIC, 100 - 4000 MHz
General Description
Features
Functional Diagram
The HMC497LP4 & HMC497LP4E are low noisehigh
linearity Direct Quadrature Modulator RFICs which
are 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 @ +5.0V 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 / HMC497LP4E is suitable for
various modulation systems:
UMTS, GSM or CDMA Basestations
Fixed Wireless or WLL
ISM Transceivers, 900 & 2400 MHz
GMSK, QPSK, QAM, SSB Modulators
