This is a compatible replacement for the infamous 1GC1-4207 , used in early-mid-2000's agilent ESA spectrum analyzers (E44xx etc) and ESG signal generators, as part of the PLL chain.
Qty 2, in unopened digi-key bag . These sell for 35$ each. Would like to get 50$ (CAD) for both, buyer pays shipping. US/CAN/Europe.
Selling because my unit has a later revision RF deck with a different prescaler MMIC.
