Hittite Intros GaAs MMIC I/Q Upconverters & Downconverters
-- Ideal for 38 GHz & 42 GHz Microwave Radio Applications
MA, 06/07/2013 – Hittite Microwave Corporation, the world class supplier of complete MMIC based
solutions for communication & military markets, has launched several new, highly integrated
I/Q upconverter and downconverter products which cover the licensed 38 GHz and 42 GHz
bands in microwave radios for cellular backhaul radio links.
the HMC6146BLC5A are
GaAs MMIC I/Q variable gain upconverters which form a competitive and cost-effective microwave
radio transmitter solution which has been designed to meet or exceed all of the performance
criteria required for modern high capacity QAM microwave radios. The
operates from 37 to 40 GHz and provides a small signal conversion gain of 10 dB with
17 dBc of sideband rejection, and 13 dB of gain control. The
operates from 40 to 44 GHz and provides a small signal conversion gain of 12 dB with 25 dBc
of sideband rejection, and 17 dB of gain control. The
the HMC6146BLC5A both
utilize a RF variable gain amplifier preceded by an I/Q mixer where the LO is driven by a x2
multiplier. IF1 and IF2 mixer inputs are provided and an external 90 degree hybrid is needed
to select the required sideband. Both I/Q upconverters feature high output IP3 of +27 dBm,
2LO/RF isolation of 15 dB, and also meet the requirements of VSAT/Satcom transmitter terminals
covering the EHF frequency band.
is a GaAs MMIC I/Q downconverter which is ideal for replacing the front end receiver section
of 38 GHz and 42 GHz microwave radio designs. The
provides a small signal conversion gain of 13 dB with 25 dBc of image rejection and utilizes
a low noise amplifier to drive the I/Q mixer where the LO is driven by a x2 multiplier. IF1
and IF2 mixer inputs are provided and an external 90 degree hybrid is needed to select the required
I/Q downconverter also features a very low noise figure of less than 3.5 dB and typical input
IP3 of 2 dBm.
The I/Q mixer design topology used for the
, HMC6146BLC5A and
is highly advantageous because it reduces the need for filtering of the unwanted sidebands.
All three devices provide a much smaller alternative to hybrid-style single sideband converter
assemblies, and they eliminate the need for wire bonding by allowing the use of surface mount
manufacturing techniques. The
, HMC6146BLC5A and
the HMC6147ALC5A are
housed in compact, 5 x 5 mm RoHS compliant SMT packages. 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 www.hittite.com.
