Description
Ground and supply vector pins.
Power supply decoupling. The supply decoupling consists of a 10 µF capacitor (C3) to
ground. C4 to C7 are bypass capacitors. C11 ac couples VREF to ground.
Input interface. The SMA labeled J1 is the input. T1 is a 1-to-1 impedance ratio balun
to transform a single-ended input into a balanced differential signal. Removing R13,
installing R12 (0 Ω), and installing an SMA connector (J2) allows driving from a
differential source. C1 and C2 provide ac coupling. C12 is a bypass capacitor. R1 and
R2 provide a differential 50 Ω input termination. R3 to R6 are used to select the input
for the pin-strappable gain. The maximum gain is R3, R4, R5, R6 = 0 Ω and R1 and R2 =
open. The middle gain is R5 and R6 = 0 Ω, R3 and R4 = open, and R1 and R2 = 50 Ω. The
minimum gain is R3 and R4 = 0 Ω, R5 and R6 = open, and R1 and R2 = 33.2 Ω.
Output interface. The SMA labeled J3 is the output. T2 is a 1-to-1 impedance ratio balun
to transform a balanced differential signal to a single-ended signal. Removing R14,
installing R15 (0 Ω), and installing an SMA connector (J4) allows differential loading. C13 is
a bypass capacitor. R7, R8, R9, and R10 are provided for generic placement of matching
components. The evaluation board is configured to provide a 200 Ω to 50 Ω impedance
transformation with an insertion loss of 17 dB. C9 and C10 provide ac coupling.
Device enabled. C8 is a bypass capacitor. When the P1 jumper is set toward the VPOS label,
the ENBL pin is connected to the supply, enabling the device. In the opposite direction,
toward the GND label, the ENBL pin is grounded, putting the device in power-down mode.
