EVALUATION BOARD
An evaluation board is available for the ADL5802. The standard evaluation board is fabricated using Rogers® RO3003 material. Each of
the RF, LO, and IF ports is configured for single-ended signaling via a balun transformer. The schematic for the evaluation board is shown
in Figure 73. Table 5 describes the various configuration options for the evaluation board. Layout for the board is shown in Figure 74 and
Figure 75.

Function
Power supply decoupling. Nominal supply decoupling
consists of a 0.01 µF capacitor to ground in parallel with 10
pF capacitors to ground, positioned as close to the device
as possible. Series resistors are provided for enhanced
supply decoupling using optional ferrite chip inductors.
RF Channel 1 and RF Channel 2 input interfaces. Input
channels are ac-coupled through C5, C12, C13, and C14. T3
and T4 are 1:1 baluns used to interface to the 50 Ω
differential inputs.
IF Channel 1 and IF Channel 2 output interfaces. The 200 Ω
open-collector IF output interfaces are biased through the
center taps of T2 and T4 4:1 impedance transformers. C15
and C16 provide local bypassing with R20 and R21 available
for additional supply bypassing. R6, R7, R13, R14, R15, and
R16 are provided for IF filtering and matching options.
LO interface. C2 and C3 provide ac coupling for the local
oscillator input. T1 is a 1:1 balun to allow single-ended
interfacing to the differential 50 Ω local oscillator input.
Enable interface. The ADL5802 can be disabled using the 3-
pin ENBL1 header. The ENBL pin is pulled up to VPOS
through R9. R1 is provided as an optional termination for
the high impedance enable interface. If desired, the ENBL
pin can be driven by an external source through the ENBL
SMA connector.
