HMC557LC4
v02.0514
GaAs MMIC FUNDAMENTAL
MIXER, 2.5 - 7.0 GHz
General Description
Features
Functional Diagram
Passive Double Balanced Topology
Wide IF Bandwidth: DC - 3 GHz
High LO/RF Isolation: 48 dB
Low Conversion Loss: 7 dB
24 Lead Ceramic 4x4mm SMT Package: 16mm2
Electrical Specications, TA = +25° C, IF= 100 MHz, LO= +15 dBm*
Typical Applications
The HMC557LC4 is ideal for:
• WiMAX & Fixed Wireless
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Test Equipment & Sensors
• Military End-Use
The HMC557LC4 is a general purpose double
balanced mixer in a leadless RoHS compliant
SMT package that can be used as an upconverter
or downconverter between 2.5 and 7 GHz. This
mixer is fabricated in a GaAs MESFET process,
and requires no external components or matching
circuitry. The HMC557LC4 provides excellent LO to
RF and LO to IF isolation due to optimized balun
structures and operates with LO drive levels as low
as +9 dBm. The RoHS compliant HMC557LC4
eliminates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.

No connection required.
These pins may be connected to RF/DC
ground without affecting performance.

3LO This pin is DC coupled
and matched to 50 Ohms.
9 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 or sink more than 2 mA of current or
part non-function and possible part failure will result.
16 RF This pin is DC coupled
and matched to 50 Ohms.

The circuit board used in this 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 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.
