Description
RF input/output – RF input or output port which is either connected via a low insertion loss path to RF common (J₁)
or isolated from RF common, according to the logic levels applied to V₁ and V₂
Equipotential point – Equipotential point for control voltage and RF circuits. Must be connected to PCB ground via
lowest possible impedance
RF input/output – RF input or output port which is either connected via a low insertion loss path to RF common (J₁)
or isolated from RF common, according to the logic levels applied to V₁ and V₂
Control voltage – Control voltage input #2
RF common input/output – RF input/output port that is connected via low insertion loss path to either RF1 or RF2,
depending upon the voltage applied to control voltage pin
Control voltage – Control voltage input #1
Evaluation Board
The evaluation board for SKY13268-344LF allows the part to be
fully exercised. The insertion loss of the transmission lines
between J₁- U1 and U1 - J₂/J₃ can be determined by measuring
the performance of the calibration through-line, which contains
two DC block capacitors in identical positions to the DC blocks
present in the main circuit.
The state of the SKY13268-344LF is controlled by applying
the appropriate logic level voltages to ports V₁ and V₂, per the
Truth Table.
