Function
Power supply decoupling. Nominal supply decoupling consists of
a 0.1 μF capacitor to ground.
Device under test.
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.
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.
Power-up interface. The
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.
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.
