Component

Description

Default Condition

R1, SW1

Device enable. When the switch is set toward the SW1 label, the ENBL pin is connected to VPOS, which

enables the ADL5511. In the opposite switch position, the ENBL pin is grounded which disables the ADL5511.

R1 = 0 Ω (Size 0402)

SW1 = towards SW1 label

C6, C10

Envelope carrier-removal filters (FLT2, FLT3). The corner frequency of the internal VENV two-pole carrier-

removal filter can be reduced by placing additional capacitors in C6 and C10.

C6, C10 = open (Size 0402)

C2

Envelope reference carrier-removal filter (FLT1). The internal filter that removes the carrier from the envelope

reference dc voltage can be augmented by placing a capacitor in C2.

C2 = 100 pF (Size 0402)

R3, R14, R15,

R16, R17

Alternate interface. The P2 edge connector provides an alternate access point to the various ADL5511 signals.

R3, R14, R15, R16, R17 = open (Size

0402)
