MIXERS - DOUBLE-BALANCED - CHIP
Functional Diagram
General Description
The HMC129 chip is a miniature double-balanced
mixer which can be used as an upconverter or down-
converter in the 4 to 8 GHz band. The chip can be
integrated directly into hybrid MICs without DC bias
or external baluns to provide an extremely compact
mixer. It is ideally suited for applications where small
size, no DC bias, and consistent IC performance are
required. This mixer can operate over a wide LO drive
input of +9 to +15 dBm. It performs equally well as a
Bi-Phase modulator or demodulator. See the HMC136
data sheet.
