Description

C1, C8, C10, C12,

C13, C15, C18,

C21, C22, C23,

C24, C25, C26

Power supply decoupling. Nominal supply decoupling consists of

a 0.01 μF capacitor to ground in parallel with 10 pF capacitors to

ground positioned as close to the device as possible.

Z1 to Z4, C2, C3,

C6, C7, C9, C11

RF main and diversity input interface. Main and diversity input

channels are ac-coupled through C9 and C11. Z1 to Z4 provide

additional component placement for external matching/filter

networks. C2, C3, C6, and C7 provide bypassing for the center taps of

the main and diversity on-chip input baluns.

T1, T2, C17, C19,

C20, C27 to C33,

L1, L2, L4, L5,

R3, R6, R9, R10

IF main and diversity output interface. The open-collector IF output

interfaces are biased through the pull-up choke inductors (L1, L2,

L4, and L5), leaving R3 and R6 available for additional supply

bypassing. T1 and T2 are 4:1 impedance transformers that are used

to provide a single-ended IF output interface, and C27 and C28

provide the center tap bypassing. C17, C19, C20, C29, C30, C31, C32,

and C33 ensure an ac-coupled output interface. Remove R9 and

R10 for balanced output operation.

C14, C16,

R15, LOSEL

LO interface. C14 and C16 provide ac coupling for the LOI1 and LOI2

local oscillator inputs. LOSEL selects the appropriate LO input for

both mixer cores. R15 provides a pull-down to ensure LOI2 is enabled

when the LOSEL jumper is removed. The jumper can be removed to

allow the LOSEL interface to be exercised by using an external logic

generator.

R19, PWDN

PWDN interface. When the PWDN 2-pin shunt is inserted, the

ADL5354 is powered down. When R19 is open, it pulls the PWDN

logic low and enables the device. The jumper can be removed to

allow PWDN interface to be exercised using an external logic

generator. Grounding the PWDN pin is allowed during nominal

operation but is not permitted when supply voltages exceed 3.3 V.

R1, R2, R4, R5, L3,

L6, R7, R8, R11 to

R14, R16, R17, C34

Bias control. R16 and R17 form a voltage divider to provide a 3 V for

logic control, bypassed to ground through C34. Resistors R7, R8, R11,

R12, R13, and R14 provide resistor programmability of VGS0, VGS1,

and VGS2. Typically, these nodes can be hardwired for nominal

operation. Grounding these pins is allowed for nominal operation.

R2 and R5 set the bias point for the internal LO buffers. R1 and R4 set

the bias point for the internal IF amplifiers. L3 and L6 are external

inductors used to improve isolation and common-mode rejection.
