HMC258LC3B
v03.0414
GaAs MMIC SUB-HARMONIC
SMT MIXER, 14.5 - 19.5 GHz
General Description
Features
Functional Diagram
The HMC258LC3B is a 14.5 - 19.5 GHz surface
mount sub-harmonically pumped (x2) MMIC mixer
with an integrated LO amplier in a SMT leadless
ceramic package. At 45 dB the 2LO to RF isolation
eliminates the need for additional ltering. The LO
amplier is a single bias (+5V) two stage design with
only 0 dBm drive requirement. The HMC258LC3B
requires no external matching components, making it
ideal for integrated subsystem applications. Utilizing
the HMC258LC3B eliminates the need for wire-
bonding, thereby providing a consistent connection
interface for the customer.
Integrated LO Amplier: 0 dBm Input
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: >45 dB
Wide IF Bandwidth: DC - 3.5 GHz
No External Matching Required
RoHS Compliant 3x3mm Ceramic SMT Package
Electrical Specications, TA = +25 °C, LO Drive = 0 dBm
Typical Applications
The HMC258LC3B is ideal for:
• Point to Point Radios
• VSAT and SATCOM
• Test & Measurement Equipment
• Military & Space

2IF
IF Port. This pin is DC coupled and should be DC blocked
externally using a series capacitor whose value has been
chosen to pass the necessary IF frequency range. Any applied
DC voltage to this pin will result in die non-function and
possible die failure.
3Vdd
Power Supply for the LO Amplier. An external RF bypass
capacitor of 100 - 330 pF is required as close to the package
as possible.
5LO LO Port. This pin is AC coupled and matched to 50 Ohms.
7 - 9 N/C This pin may be connected to the housing
ground or left unconnected.

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
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
