Passive Double Balanced Topology
High LO/RF Isolation: 50 dB
Low Conversion Loss: 7 dB
Wide IF Bandwidth: DC - 5 GHz
RoHS Compliant 3x3 mm SMT Package
Electrical Specifications,

A
= +25 C, IF= 100 MHz, LO= +13 dBm*
Typical Applications
The HMC553LC3B is ideal for:
Point-to-Point Radios
Point-to-Mulit-Point Radios
Test Equipment & Sensors
Military End-Use
The HMC553LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant SMT
package that can be used as an upconverter or
downconverter between 7 and 14 GHz. This mixer
is fabricated in a GaAs MESFET process, and
requires no external components or matching cir-
cuitry. The HMC553LC3B 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 HMC553LC3B elim-
inates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.

This pin is DC coupled and matched to 50 Ohm
from 7 to 14 GHz.
5
IF
This pin is DC coupled. For applications not requiring opera-
tion 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.

This pin is DC coupled and matched to 50 Ohm
from 7 to 14 GHz.

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

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 suffi 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.
