Components

Function

Default Conditions

C2 to C5, C7, C9, C17

Power supply decoupling. Nominal supply decoupling consists of

a 0.1 μF capacitor to ground.

C2 = 10 μF (Size C7343)

C3 to C5, C7, C9, C17 = 0.1 μF (Size 0603)

U1

Device under test.

Installed

INB−

T2

J1

C1

R3, R4, R9 to R13

Input interface. INB− is the RF input. T2 is a 3:1 impedance ratio balun

used to transform a single ended 50 Ω signal into a 150 Ω balanced

differential signal. The input can be configured for a differential by

removing R3 and installing a 0 Ω jumper at R4.

C1 provides dc blocking. R12 and R13 are placeholders and can be

replaced with blocking capacitors when driving the ADL5201 from

a fully differential source.

R3 grounds one side of the differential drive interface for single-ended

applications. R9, R10, and R11 are provided for generic placement of

matching components.

T2 = TC3-1T+ (Mini-Circuits)

C1 = 0.1 μF (Size 0402)

R3, R12, R13 = 0 Ω (Size 0402)

L1, L2

R19, R20, R24 to R28,

R47, R48, R51

OUTB+, OUTB−

Output interface. T1 is a 3:1 impedance ratio balun used to transform

a 150 Ω balanced differential signal to a 50 Ω singled-end signal.

C10 and C11 are dc blocks.

L1 and L2 provide dc bias to the open-collector output.

R24 to R28 are provided for the generic placement of matching

components. R47 grounds one side of the differential output interface

for single-ended applications.

T1 = TC3-1T+ (Mini-Circuits)

C10 to C12 = 0.1 μF (Size 0402)

R19, R20, R24 to R26, R47, R51 = 0 Ω

L1, L2 = 1 μH (Size 0805)

OUTB+ (SMA connector) installed

OUTB− (SMA connector) installed

PWUP, PWRUP

Power-up interface. The ADL5201 is powered up by applying a logic

high (1.4 V ≤ PWUPA/B ≤ 3.3 V) to PWUP from an external source or by

installing a shunt between Pin 1 and Pin 2 of the 3-pin header, PWUP.

R14 to R18, R21 to R23,

R30 to R38, R42, R43, R46

C6, C8, C13 to C16

Gain control interface. All of the gain control functions are fully

controlled via the USB microcontroller using the supplied software.

Three-pin headers allow for manual operation of the gain control, if

desired.

R1, R2, R5 to R8, R14, R15, R17, R18, R22, R23, R34 to R38, R42, R43, and

R46 isolate the digital control pins from the microcontroller and

provide current limiting.

The R16, R21, and R30 to R33 resistors and the C6, C8, and C13 to C16

capacitors allow for the generic placement of filter components.
