I have a question aout pin connection of HMC5929LS6.
According to Pin Description in the datasheet of HMC5929LS6, Pin 2, 5, 10 and 13 should be connected RF/DC bround on the board. But in the figure of Evaluation PCB in the detasheet, pin 2 and 10 don't seem to connect ground. Instead of connectting to ground, they can be added external bias or something from J5 and J6. Which is recommended connection about pin 2 and 10, ground or adding something bias voltage?
