HMC904LC5
v02.0511
GaAs MMIC I/Q DOWNCONVERTER
17 - 24 GHz
General Description
FeaturesTypical Applications
The HMC904LC5 is a compact GaAs MMIC I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 12 dB with a noise gure of 3 dB
and 30 dB of image rejection across the frequency
band. The HMC904LC5 utilizes an LNA followed by
an image reject mixer which is driven by an active x2
multiplier. The image reject mixer eliminates the need
for a lter following the LNA, and removes thermal
noise at the image frequency. I and Q mixer outputs
are provided and an external 90° hybrid is needed to
select the required sideband. The HMC904LC5 is a
much smaller alternative to hybrid style image reject
mixer downconverter assemblies, and is compatible
with surface mount manufacturing techniques.

N/C
The pins are not connected internally; however, all data
shown herein was measured with these pins connected
to RF/DC ground externally.
3VDLO2 Power supply for second stage of LO amplier.
7VDRF Power supply for RF LNA.
10, 19, 24, 29 GND These pins and the exposed ground
paddle must be connected to RF/DC ground.
11 RF This pin is AC coupled
and matched to 50 Ohms
20 IF2 This pin is DC coupled. For applications not requir-
ing operation to DC this port should be DC blocked
externally using a series capacitor whose value has
been chosen to pass the necessary frequency range.
For operation to DC, this pin must not sink / source more
than 3 mA of current or part non-function and possible
failure will result.
23 IF1
30 LO This pin is AC coupled
and matched to 50 Ohms.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
