General Description
Mimix Broadband’s 17.0-25.0 GHz GaAs MMIC transmitter has a
+13.0 dBm output P1dB and 20.0 dB image rejection across the
band. This device is an image reject sub-harmonic anti-parallel
diode mixer followed by a balanced two stage output amplifier
and includes an integrated LO buffer amplifier. The image reject
mixer reduces the need for unwanted sideband filtering before
the power amplifier. The use of a sub-harmonic mixer makes the
provision of the LO easier than for fundamental mixers at these
frequencies. I and Q mixer inputs are provided and an external
90 degree hybrid is required to select the desired sideband. This
MMIC uses Mimix Broadband’s 0.15
µm
GaAs PHEMT device
model technology, and is based upon electron beam
lithography to ensure high repeatability and uniformity. The
device comes in a 7x7mm QFN surface mount laminate
package that is RoHS compliant. This device is well suited for
Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT
applications.
