We purchased an evaluation board of HMC460LC5. After receiving the product, we tested it. But it can not amplify the test signal, we want to why? The detailed test report is attached.
Moved this question to RF and Microwave community. Someone here will be able to help you better.
137mA current is quiet high than the typical value. What are the power up and down bias sequences you follow?
What is the iimpedance that HMC460LC5 EVB`s RFIN port sees? i.e. DAC output impedance?
As it says on the DS RF I/O pins of HMC460 is DC coupled, so you cannot apply DC offset level other than 0V. If you need to do that, you need to use series DC block CAPS to remove the DC at the RF I/O pins of HMC460.
