Product Number: HMC345A
We are using 3 signals connected to 3 different GHz frequencies which are around 6.8GHz. a 3.3 to 5V logic translator drive the CtrlA and ctrlB pins on the board.
When tried to switch there is no output and leaks all three signals around -40dB at the output.
A 1pF coupling capacitors are present at the output and input.
2k resistor and 5pf are present on the Vdd pins and NC, GND pins are grounded.
Everything seems fine on schematics and layout but doesnt switch or pass through the complete signal through from the ports
