HMC552LP4 / 552LP4E
GaAs MMIC MIXER w/ INTEGRATED
LO AMPLIFIER, 1.6 - 3.0 GHz
v03.1210
General Description
Features
Functional Diagram
The HMC552LP4 & HMC552LP4E are high linearity,
double-balanced converter ICs that operate from
1.6 to 3.0 GHz and deliver a +25 dBm input third
order intercept point. The LO amplier output and
high dynamic range mixer input are positioned so
that an external LO lter can be placed in series
be-tween them. The converter provides 30 dB of
LO to RF isolation and is ideal for upconverter and
down-converter applications. The IC operates from
a single +5V supply consuming 62 mA of current
and accepts a LO drive level of -4 to +4 dBm. The
design requires no external baluns and supports
IF frequencies between DC and 1 GHz. The
HMC552LP4 & HMC552LP4E are pin for pin com-
patible with the HMC551LP4 & HMC551LP4E, which
operate from 0.8 to 1.2 GHz.
Input IP3: +25 dBm
Low Input LO Drive: -4 to +4 dBm
LO to RF Isolation: 30 dB
Low Conversion Loss: 8 dB

Pin Number Function Description Interface Schematic
1 MIX LO This pin is DC coupled and matched to 50 Ohms.
An off chip DC blocking capacitor is required.
2, 6 - 9,
11 - 17, 19 - 24 N/C No connection. These pins may be connected to RF
ground. Performance will not be affected.
3 BIAS
Power supply for the LO amplier , a Bias resistor is
required . Three external bypass capacitors are recom-
mended for optimum performance, as illustrated in the
application circuit.
4 GND Backside of package has exposed metal ground
paddle that must also be connected to ground.
5 LO This pin is DC coupled and matched to 50 Ohms.
An off chip DC blocking capacitor is required.
10 IF
This pin is DC coupled. For applications not requiring
operation to DC, this port should be DC blocked
externally using a series capacitor whose value has
been chosen to pass the necessary IF frequency
range. For operation to DC, this pin must not source/
sink more than 18 mA of current or die non-function
and possible die failure will result.
18 RF This pin is DC 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 Hit-
tite upon request.
