Functional Diagram
General Description
The HMC129 chip is a miniature double-bal-
anced mixer which can be used as an upcon-
verter or downconverter in the 4 to 8 GHz band.
The chip can be integrated directly into hybrid
MICs without DC bias or external baluns to pro-
vide 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.
