Typical Applications
The HMC128 is a miniature double-balanced
mixer chip that can be used as an upconverter
or downconverter. The device is a passive diode/
balun type mixer with high dynamic range. Noise
fi gure is essentially equal to the conversion loss.
The mixer can handle larger signal levels than
active mixers due to the high third order inter-
cept. MMIC implementation provides exceptional
balance in the circuit resulting in high LO/RF and
LO/IF isolations. This mixer can operate over a
wide LO Drive input of +9 to +15 dBm.
The HMC128 is ideal for:

Interface Schematic
1
LO
This pin is DC coupled and matched to 50 Ohm
from 1.8 to 5.0 GHz.
2
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 2mA of current or die non-
function and possible die failure will result.
3
RF
This pin is DC coupled and matched to 50 Ohm
from 1.8 to 5.0 GHz.
GND
The backside of the die must connect to RF ground.
