HMC294 is a miniature passive GaAs MMIC double-balanced mixer chip produced by Hittite Corporation. It has excellent isolation and requires no external components or DC bias. It can be used as an upconverter or downconverter from 25 to 40 GHz.
The document describes the HMC294, a miniature passive GaAs MMIC double-balanced mixer designed for frequencies between 25 and 40 GHz. It functions as an upconverter or downconverter without requiring DC bias due to on-chip baluns that provide excellent isolation. The chip is suitable for applications such as microwave point-to-point radios, LMDS, and SATCOM.
| Frequency Range, RF & LO | 25 - 40 GHz |
|---|---|
| Frequency Range, IF | DC - 2 GHz |
| Conversion Loss (Typical) | 13 dB |
| Noise Figure (SSB) (Typical) | 13 dB |
| LO to RF Isolation (Typical) | 27 dB |
| Input IP3 (Typical) | +20 dBm |
| Operating Temperature | -55 to +125 °C |
The mixer operates from 25 to 40 GHz for both RF and LO inputs.
The die should be attached directly to a ground plane eutectically or with conductive epoxy.
