General Description
Features
Functional Diagram
Passive: No DC Bias Required
Input IP3: +20 dBm
LO/RF Isolation: 40 dB
Wide IF Bandwidth: DC - 8 GHz
12 Lead Ceramic 3x3 mm SMT Package: 9mm2
Electrical Speci cations, TA = +25° C, IF= 1 GHz, LO= +13 dBm*
Typical Applications
The HMC260LC3B is ideal for:
• Point-to-Point Radios
• Point-to-Mulit-Point Radios & VSAT
• Test Equipment & Sensors
• Military End-Use
The HMC260LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant
SMT package that can be used as an upconverter
or downconverter between 14 and 26 GHz. This
mixer requires no external components or matching
circuitry. The HMC260LC3B provides excellent LO to
RF and LO to IF suppression due to optimized balun
structures. The mixer operates with LO drive levels
above +9 dBm. The HMC260LC3B eliminates the
need for wire bonding, allowing use of 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 Ohm.
5IF
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.
8RF This pin is DC coupled
and matched to 50 Ohm.
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 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 board should be mounted to an appro-
priate heat sink. The evaluation circuit board shown
is available from Hittite upon request.
