GaAs MMIC FUNDAMENTAL
MIXER, 5.5 - 14.0 GHz
General Description
Features
Functional Diagram
Passive Double Balanced Topology
High LO/RF Isolation: 45 dB
Low Conversion Loss: 7 dB
Wide IF Bandwidth: DC - 6 GHz
12 Lead Ceramic 3x3mm SMT Package: 9mm2
Electrical Specications, TA = +25° C, IF= 100 MHz, LO= +15 dBm*
Typical Applications
The HMC558LC3B is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Test Equipment & Sensors
• Military End-Use
The HMC558LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant SMT
package that can be used as an upconverter or
downconverter between 5.5 and 14 GHz. This mixer
is fabricated in a GaAs MESFET process, and
requires no external components or matching cir-
cuitry. The HMC558LC3B 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 HMC558LC3B elim-
inates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.

Pin Number Function Description Interface Schematic
1, 3, 4, 6, 7, 9 GND Package bottom must also be connected to RF/DC ground.
2LO This pin is DC coupled
and matched to 50 Ohms.
5 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.
8 RF This pin is DC coupled
and matched to 50 Ohms.
10, 11, 12 N/C No connection required. These pins may be connected to RF/
DC ground without affecting performance.

[2] Circuit Board Material: Arlon 25 RF
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.
