HMC558
GaAs MMIC FUNDAMENTAL
MIXER, 5.5 - 14 GHz
v01.1007
General Description
Features
Functional Diagram
High LO/RF Isolation: 45 dB
Passive Double Balanced Topology
Low Conversion Loss: 7 dB
Wide IF Bandwidth: DC - 6 GHz
Small Size: 0.91 x 0.94 x 0.1 mm
Typical Applications
The HMC558 is ideal for:
Microwave Radio
Military & Space
Communications, Radar & EW
Test Equipment & Sensors
The HMC558 is a passive double balanced mixer
that can be used as an upconverter or downconverter
between 5.5 and 14 GHz. The miniature monolithic
mixer is fabricated in a GaAs MESFET process, and
requires no external components or matching circu-
itry. The HMC558 operates with LO drive levels as
low as +9 dBm and provides excellent LO to RF and
LO to IF isolation due to optimized balun structures.
Measurements were made with the chip mounted
into in a 50 ohm test fixture and includes the para-
sitic effects of wire bond assembly. Connections were
made with a 1 mil wire bond with minimal length (<12
mil).
