Eval - cn028 - eb1z problem

Question asked by liulian on Mar 28, 2018

1. Eval-cn028-eb1z for 5.5V power, test IBBP, IBBN, QBBP, QBBN port voltage of DC 1.72V, normal?
2. Input 1MHz sine wave signal on the IBBP port (there is no 0.5v dc offset). The output of ADF4351 is 1800MHz, and 1799MHz signal is tested at the RFOUT port, and the level is -84dbm. 1800MHz signal, the level is -37dbm; 1801MHz signal, the level is -84dbm, why is the power so small?
