Hi all,
Is the LO port capable of DC input @ HMC521A ?
Both the RF and LO ports are written in the data sheet as "This pin is AC coupled and matched to 50Ω."
We are confused by the notation of the input terminating resistor (50Ω?).
Is the LO interface schematic in the datasheet really correct?
I guess the correct circuit is similar to the RF interface schematic.
Best regards,
sss
Hi all,
We found the HMC521LC4 (EOL) datasheet to see the difference in the LO interface schematic.
The LO interface schematics of the HMC521LC4 and HMC521ALC4 are different.
The description of the pin overview is the same and inconsistent.
Which is correct, the LO interface schematic of the HMC521ALC4 or the description of the pin overview?
Is the LO pin really AC coupled?
