HMC557
GaAs MMIC FUNDAMENTAL
MIXER, 2.5 - 7.0 GHz
Features
High LO/RF Isolation: 48 dB
Wide IF Bandwidth: DC - 3 GHz
Passive Double Balanced Topology
Low Conversion Loss: 7 dB
Small Size: 1.02 x 0.94 x 0.1 mm
General Description
The HMC557 is a passive double balanced mixer
that can be used as an upconverter or downconverter
between 2.5 and 7 GHz. The miniature monolithic
mixer is fabricated in a GaAs MESFET process, and
requires no external components or matching cir-
cuitry. The HMC557 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 parasitic
effects of wire bond assembly. Connections were
made with a 1 mil wire bond with minimal length (<12
mil).
Electrical Specifications, TA = +25° C, IF= 100 MHz, LO= +15 dBm*

Description
This pin is DC coupled
and matched to 50 Ohms.

Die Bottom
This pin is DC coupled
RF
and matched to 50 Ohms.
IF
GND
This pad 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.
Die bottom must be connected to RF/DC ground.
