HMC404
GaAs MMIC SUB-HARMONICALLY
PUMPED IRM MIXER, 26 - 33 GHz
v02.1001
General Description
Features
Functional Diagram
The HMC404 chip is a sub-harmonically pumped
(x2) MMIC image rejection mixer with an integrated
LO amplifi er which can be used as an upconverter
or downconverter. The chip utilizes a GaAs PHEMT
technology that results in a small overall chip area of
2.31mm
2
. The on-chip 90 hybrid provides excellent
amplitude and phase balance resulting in greater
than 22 dB of image rejection. The LO amplifi er is a
single bias (+4V) two stage design with only +2 dBm
nominal drive required.
Integrated LO Amplifi er: +2 dBm Input
Sub-Harmonically Pumped (x2) LO
Image Rejection: 22 dB
Small Size: 1.24mm x 1.86mm
Electrical Specifi cations,
T
A
= +25 C
Typical Applications
The HMC404 is ideal for:
26 to 33 GHz Microwave Radios
Up and Down Converter for
Point to Point Radios
Satellite Communication Systems
* Unless otherwise noted, all measurements performed as downconverter.
