C31

AC-coupling capacitor connects ADL5385 VOUT to

RF_OUT RF connector or to ADL5601 RF input.

C31 = 0.1 μF

C47

AC-coupling capacitor connects ADL5601 RFOUT to

AMP_OUT connector.

C47 = 0.1 μF

R40

Resistor connects ADL5385 VOUT to RF_OUT SMA. To

check ADL5385 performance itself, insert a 0 Ω at R40 and

open R25. To check ADL5601 performance itself, insert a

0 Ω at R40 and be inserted 0.1 μF on R25, open C31.

R40 = open

R25

Resistor connects ADL5385 VOUT to ADL5601 RFIN.

R25 = 0 Ω

RTEMP

Resistor connects ADL5385 TEMP to TEMP test clip lead.

RTEMP = 200 Ω

DC bias inductor.

L8 = 470 nH

C3, C4, C5, C6, C8, C9, C11,

C43, C44, C45

Power supply bypassing capacitors.

C3 = 10 μF,

C4, C6, C8 = 0.1 μF, C5, C9, C11 = 100 pF,

C43 = 1 μF, C44 = 1.2 nF, C45 = 68 pF

Resistor to share power supply between the ADL5385 and

the ADL5601. To turn on the ADL5601 with the power

supply on VP1, install a 0 Ω resistor in this location.

R8 = open

ADL5385 quadrature modulator.

ADL5385

SOT-89 RF/IF gain block.
