Winner: Name that Ware November 2018

The Ware for November 2018 is a bias/control board for the HP 2-18GHz YIG-tuned multiplier. I really appreciate this fascinating ware, it reminds me that the MOS transistor is not the be-all and end-all of electronics. Of course, every day we encounter crystals as frequency references, and those are literally shaved pieces of quartz, but here is a sphere of Yttrium Iron Garnet (YIG) being used as a tunable RF filter. Thanks to phantom deadline for contributing this ware, and also congrats to Brian for nailing the ware. Email me for your prize!
