Default Conditions
C1, C4, C6, C7, C8, C9, C10,
C11, C17, C18, R10, R12,
R19, R20, R21
Power Supply Decoupling. Nominal supply decoupling consists a
0.01 μF capacitor to ground in parallel with 10pF capacitors to
ground positioned as close to the device as possible. Series resistors
are provided for enhanced supply decoupling using optional ferrite
chip inductors.
C6, C7, C8 = 10pF (size 0402)
C9, C10, C11 = 0.01 μF (size 0402)
C1, C4, C17, C18 = open (size 0402)
R10, R12, R19, R20, R21 = 0
Ω (size
0402)
C5, C12, C13, C14, T3, T5,
RF1, RF2
RF Channel 1 and 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.
C5, C12, C13, C14 = 1nF (size 0402)
T3, T5 = ETC1-1-13 (M/A-Com)
C15, C16,
L1, L2, L3, L4,
R2, R3, R6, R7, R13, R14,
R15, R16, R20, R21,
T2, T4,
IF1, IF2
IF Channel 1 and Channel 2 Output Interfaces. The 200-
Ω open
collector IF output interfaces are biased through the center taps of
4:1 impedance transformers at T2 and T4. C15 and C16 provide local
bypassing with R20 and R21 available for additional supply
bypassing. L1, L2, L3, and L4 provide the options when pull-up
choke inductors are used to bias the open-collector outputs. R6, R7,
R13, R14, R15, and R16 are provided for IF filtering and matching
options.
C15, C16 = 100pF (size 0402)
L1, L2, L3, L4 = open (size 0805)
R2, R3, R13, R14, R15, R16, R20, R21 =
0
Ω (size 0402)
R6, R7 = open (size 0402)
T2, T4 = TC4-1W+ (MiniCircuits)
C2, C3, R4, R5, T1, LO
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. R4 and R5 provide the options
when differential LO interfaces are needed.
C2, C3 = 1nF (size 0402)
R4, R5 = 0
Ω (size 0402)
T1 = ETC1-1-13 (M/A-Com)
R1, R9, R11, ENBL1
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 impendace enable
interface.
R9 = 10k
Ω (size 0402)
R11 = 0
Ω (size 0402)
R1 = open (size 0402)
ENBL1 = 3-pin header and shunt
R22, R23, VSET
VSET Bias Control. R22 and R23 form an optional resistor divider
network between VPOS and GND, allowing for a fixed bias setting.
The default values are set up for 3.8 V at the VSET pin.
R22 = 866
Ω (size 0402)
R23 = 10k
Ω (size 0402)
