Martein Bakker, PA3AKE, has designed an incredibly high performance receiver front-end for ham radio that utilizes an advanced H-mode mixer. I purchased a set of PCBs and Quartz Crystal filters from him last March, and this November I finally got around to updating the Bill of Materials to reflect currently available parts.
Read about the front-end at Martein's page here: H-Mode Mixer Frontend
I hope to describe the build as it progresses, but in the meantime, I'm making the updated BOM available here as Excel spreadsheets with part numbers for Digikey and Mouser - two large distributors here in the US. Hopefully this information will make it easier to find all the parts needed to complete the front-end.
Currently, the biggest missing piece is the Local Oscillator - if I can find the time and motivation, I hope to complement Martein's work on an AD9910 board, with one using the AD9914. The performance trade-off is not clear to me, and it may be a futile effort, but the incredible speed of the AD9914 makes it interesting for other work at higher frequencies.
I have tried to follow as closely as possible the organization Martein lays out on his page - thus making it easy to find the correct BOM for the board of interest.

The motherboard has mainly connectors on it, as it hosts the individual bandpass boards as well as the I2C, Attenuator, and IF notch boards.
The single frontend board contains both the H-Mode mixer itself and the quartz crystal roofing filters
