Hittite's New High Linearity Wideband Direct Modulator for 3G & 4G Applications
February 22, 2012 Press Release
-- Excellent OIP3 & Low Noise from 100 MHz to 6 GHz!
MA, 02/22/2012 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets, has launched a new high linearity Wideband Direct I/Q Modulator HMC1097LP4 which
is ideal for automotive, broadband, cellular/3G, WiMAX/LTE/4G, military and test & measurement equipment
applications between 100 MHz and 6 GHz.
Hittite Microwave Corporation is an innovative designer and manufacturer of high performance integrated
circuits, or ICs, modules, subsystems and instrumentation for technically demanding digital, RF, microwave and
millimeterwave applications covering DC to 110 GHz. The Company's standard and custom products apply analog,
digital and mixed-signal semiconductor technologies, which are used in a wide variety of wireless / wired
communication and sensor applications for Automotive, Broadband, Cellular Infrastructure, Fiber Optics &
Networking, Microwave & Millimeterwave Communications, Military, Test & Measurement, and Space markets. The
Company is headquartered in Chelmsford, Massachusetts.Contact
is a high linearity, low noise Direct Quadrature Modulator RFIC which is rated from 100 MHz to 6 GHz. This
wideband direct modulator exhibits an outstanding output IP3 of +30 dBm, noise floor of -160 dBm/Hz, output P1dB
of +11 dBm, and sideband suppression of -46 dBc. The RF output port is single-ended and matched to 50 Ohms with no
external components while the LO input operates from drive levels between -6 dBm and +6 dBm, and can be driven in
either differential or single-ended mode. The
HMC1097LP4Ehas a flexible architecture where its output IP3 can be further optimized over different
frequencies up to 6 GHz. The
exhibits a very fast enable/disable feature which can be used to reduce system power dissipation in TDD-based
cellular communication systems.
Optimized for a +5V supply, and housed in a compact 4 x 4 mm SMT QFN
requires minimal external components and provides a low cost alternative to more complicated double upconversion
architectures. This high linearity direct modulator can be used to create virtually any analog or digital
modulation format including BPSK, QPSK, 8PSK, OFDM, and QAM for basestation, access point, and customer premise
equipment. Ideal for software defined radio and multi-band transmitter applications, the
offers improved carrier feedthrough and sideband suppression characteristics. The device also supports
applications where upconverter modulation format and/or output frequency must be dynamically changed based on
local operating conditions.
Samples and evaluation PC boards for all SMT packaged products are available
from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets
are available on-line at
