Preliminary Technical Data
EVALUATION BOARD
An evaluation board is available for the family of double balanced mixers, including ADL5355 and ADL5357. The standard evaluation
board schematic is presented in Figure 8. The evaluation board is fabricated on a multilayer Rogers board. Table 4 details the various
configuration options of the evaluation board.

Function
Power Supply Decoupling. Nominal supply decoupling consists a 10
μF capacitor to ground in parallel with 10pF capacitors to ground
positioned as close to the device as possible.
RF Input Interface. The input channels is ac-coupled through C1. C4
and C5 provide bypassing for the center taps of the RF input baluns.
IF Output Interface. The open collector IF output interfaces are
biased through pull-up choke inductors L4 and L5. T1is a 4:1
impedance transformer used to provide a single ended IF output
interface, with C17 providing center-tap bypassing. R1 should be
