HMC552LP4 / 552LP4E
GaAs MMIC MIXER w/ INTEGRATED
LO AMPLIFIER, 1.6 - 3.0 GHz
v00.0306
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 ampli er 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 compatible 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
Single Positive Supply: +5V @ 62 mA
RoHS Compliant 4x4 mm QFN Package

Pin Number Function Description Interface Schematic
1MIX LO
This pin is DC coupled and matched to 50 Ohms from
1.6 to 3.0 GHz. 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.
3BIAS
Power supply for the second stage LO ampli er. Three
external bypass capacitors are recommended for
optimum performance, as illustrated in the application
circuit.
4GND
Backside of package has exposed metal ground
paddle that must also be connected to ground.
5LO
This pin is DC coupled and matched to 50 Ohms from
1.6 to 3.0 GHz. 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 exter-
nally 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 from 1.6 to 3.0 GHz.

Evaluation PCB
The circuit board used in the  nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A suf cient 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.
