Functional Diagram
General Description
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
figure 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.
